Delete the repo contents. Add a README.

flutter/engine now depends directly on the chrome fork. The contents of this repo are triggering false-alarms by overzealous security scanners. We need to keep this repo around to avoid breaking checkouts of old versions of fluttter/engine. This CL deletes the contents to avoid triggering scanners, and not break old checkouts.

-Description:
-"A massively spiffy yet delicately unobtrusive compression library."
-
-zlib is a free, general-purpose, legally unencumbered lossless data-compression
-library. zlib implements the "deflate" compression algorithm described by RFC
-1951, which combines the LZ77 (Lempel-Ziv) algorithm with Huffman coding. zlib
-also implements the zlib (RFC 1950) and gzip (RFC 1952) wrapper formats.
-
-Local Modifications:
- - Only source code from the zlib distribution used to build the zlib and
-   minizip libraries are present. Many other files have been omitted. Only *.c
-   and *.h files from the upstream root directory and contrib/minizip were
-   imported.
- - The contents of the google directory are original Chromium-specific
-   additions.
- - Added chromeconf.h
- - Plus the changes in 'patches' folder.
- - Code in contrib/ other than contrib/minizip was added to match zlib's
-   contributor layout.

- *
- * Per http://en.wikipedia.org/wiki/Adler-32 the adler32 A value (aka s1) is
- * the sum of N input data bytes D1 ... DN,
- *
- *   A = A0 + D1 + D2 + ... + DN
- *
- * where A0 is the initial value.
- *
- * SSE2 _mm_sad_epu8() can be used for byte sums (see http://bit.ly/2wpUOeD,
- * for example) and accumulating the byte sums can use SSE shuffle-adds (see
- * the "Integer" section of http://bit.ly/2erPT8t for details). Arm NEON has
- * similar instructions.
- *
- * The adler32 B value (aka s2) sums the A values from each step:
- *
- *   B0 + (A0 + D1) + (A0 + D1 + D2) + ... + (A0 + D1 + D2 + ... + DN) or
- *
- *       B0 + N.A0 + N.D1 + (N-1).D2 + (N-2).D3 + ... + (N-(N-1)).DN
- *
- * B0 being the initial value. For 32 bytes (ideal for garden-variety SIMD):
- *
- *   B = B0 + 32.A0 + [D1 D2 D3 ... D32] x [32 31 30 ... 1].
- *
- * Adjacent blocks of 32 input bytes can be iterated with the expressions to
- * compute the adler32 s1 s2 of M >> 32 input bytes [1].
- *
- * As M grows, the s1 s2 sums grow. If left unchecked, they would eventually
- * overflow the precision of their integer representation (bad). However, s1
- * and s2 also need to be computed modulo the adler BASE value (reduced). If
- * at most NMAX bytes are processed before a reduce, s1 s2 _cannot_ overflow
- * a uint32_t type (the NMAX constraint) [2].
- *
- * [1] the iterative equations for s2 contain constant factors; these can be
- * hoisted from the n-blocks do loop of the SIMD code.
- *
- * [2] zlib adler32_z() uses this fact to implement NMAX-block-based updates
- * of the adler s1 s2 of uint32_t type (see adler32.c).

-
-   This code is a modified version of crypting code in Infozip distribution
-
-   The encryption/decryption parts of this source code (as opposed to the
-   non-echoing password parts) were originally written in Europe.  The
-   whole source package can be freely distributed, including from the USA.
-   (Prior to January 2000, re-export from the US was a violation of US law.)
-
-   This encryption code is a direct transcription of the algorithm from
-   Roger Schlafly, described by Phil Katz in the file appnote.txt.  This
-   file (appnote.txt) is distributed with the PKZIP program (even in the
-   version without encryption capabilities).
-
-   If you don't need crypting in your application, just define symbols
-   NOCRYPT and NOUNCRYPT.
-
-   This code support the "Traditional PKWARE Encryption".
-
-   The new AES encryption added on Zip format by Winzip (see the page
-   http://www.winzip.com/aes_info.htm ) and PKWare PKZip 5.x Strong
-   Encryption is not supported.

-         Changes
-
-    Oct-2009 - Defined ZPOS64_T to fpos_t on windows and u_int64_t on linux. (might need to find a better why for this)
-    Oct-2009 - Change to fseeko64, ftello64 and fopen64 so large files would work on linux.
-               More if/def section may be needed to support other platforms
-    Oct-2009 - Defined fxxxx64 calls to normal fopen/ftell/fseek so they would compile on windows.
-                          (but you should use iowin32.c for windows instead)

-  Decryption code comes from crypt.c by Info-ZIP but has been greatly reduced in terms of
-  compatibility with older software. The following is from the original crypt.c.
-  Code woven in by Terry Thorsen 1/2003.

-  See the accompanying file LICENSE, version 2000-Apr-09 or later

-        crypt.c (full version) by Info-ZIP.      Last revised:  [see crypt.h]
-
-  The encryption/decryption parts of this source code (as opposed to the
-  non-echoing password parts) were originally written in Europe.  The
-  whole source package can be freely distributed, including from the USA.
-  (Prior to January 2000, re-export from the US was a violation of US law.)
-
-        This encryption code is a direct transcription of the algorithm from
-  Roger Schlafly, described by Phil Katz in the file appnote.txt.  This
-  file (appnote.txt) is distributed with the PKZIP program (even in the
-  version without encryption capabilities).

-        Changes in unzip.c
-
-        2007-2008 - Even Rouault - Addition of cpl_unzGetCurrentFileZStreamPos
-  2007-2008 - Even Rouault - Decoration of symbol names unz* -> cpl_unz*
-  2007-2008 - Even Rouault - Remove old C style function prototypes
-  2007-2008 - Even Rouault - Add unzip support for ZIP64
-
-        Copyright (C) 2007-2008 Even Rouault
-
-
-        Oct-2009 - Mathias Svensson - Removed cpl_* from symbol names (Even Rouault added them but since this is now moved to a new project (minizip64) I renamed them again).
-  Oct-2009 - Mathias Svensson - Fixed problem if uncompressed size was > 4G and compressed size was <4G
-                                should only read the compressed/uncompressed size from the Zip64 format if
-                                the size from normal header was 0xFFFFFFFF
-  Oct-2009 - Mathias Svensson - Applied some bug fixes from paches recived from Gilles Vollant
-        Oct-2009 - Mathias Svensson - Applied support to unzip files with compression mathod BZIP2 (bzip2 lib is required)
-                                Patch created by Daniel Borca
-
-  Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer

-         For more info read MiniZip_info.txt
-
-         Changes
-   Oct-2009 - Mathias Svensson - Remove old C style function prototypes
-   Oct-2009 - Mathias Svensson - Added Zip64 Support when creating new file archives
-   Oct-2009 - Mathias Svensson - Did some code cleanup and refactoring to get better overview of some functions.
-   Oct-2009 - Mathias Svensson - Added zipRemoveExtraInfoBlock to strip extra field data from its ZIP64 data
-                                 It is used when recreting zip archive with RAW when deleting items from a zip.
-                                 ZIP64 data is automatically added to items that needs it, and existing ZIP64 data need to be removed.
-   Oct-2009 - Mathias Svensson - Added support for BZIP2 as compression mode (bzip2 lib is required)
-   Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer

-   Decode literal, length, and distance codes and write out the resulting
-   literal and match bytes until either not enough input or output is
-   available, an end-of-block is encountered, or a data error is encountered.
-   When large enough input and output buffers are supplied to inflate(), for
-   example, a 16K input buffer and a 64K output buffer, more than 95% of the
-   inflate() execution time is spent in this routine.
-
-   Entry assumptions:
-
-        state->mode == LEN
-        strm->avail_in >= INFLATE_FAST_MIN_INPUT (6 or 8 bytes)
-        strm->avail_out >= INFLATE_FAST_MIN_OUTPUT (258 bytes)
-        start >= strm->avail_out
-        state->bits < 8
-        (state->hold >> state->bits) == 0
-        strm->next_out[0..strm->avail_out] does not overlap with
-              strm->next_in[0..strm->avail_in]
-        strm->state->window is allocated with an additional
-              CHUNKCOPY_CHUNK_SIZE-1 bytes of padding beyond strm->state->wsize
-
-   On return, state->mode is one of:
-
-        LEN -- ran out of enough output space or enough available input
-        TYPE -- reached end of block code, inflate() to interpret next block
-        BAD -- error in block data
-
-   Notes:
-
-    INFLATE_FAST_MIN_INPUT: 6 or 8 bytes
-
-    - The maximum input bits used by a length/distance pair is 15 bits for the
-      length code, 5 bits for the length extra, 15 bits for the distance code,
-      and 13 bits for the distance extra.  This totals 48 bits, or six bytes.
-      Therefore if strm->avail_in >= 6, then there is enough input to avoid
-      checking for available input while decoding.
-
-    - The wide input data reading option reads 64 input bits at a time. Thus,
-      if strm->avail_in >= 8, then there is enough input to avoid checking for
-      available input while decoding. Reading consumes the input with:
-
-          hold |= read64le(in) << bits;
-          in += 6;
-          bits += 48;
-
-      reporting 6 bytes of new input because |bits| is 0..15 (2 bytes rounded
-      up, worst case) and 6 bytes is enough to decode as noted above. At exit,
-      hold &= (1U << bits) - 1 drops excess input to keep the invariant:
-
-          (state->hold >> state->bits) == 0
-
-    INFLATE_FAST_MIN_OUTPUT: 258 bytes
-
-    - The maximum bytes that a single length/distance pair can output is 258
-      bytes, which is the maximum length that can be coded.  inflate_fast()
-      requires strm->avail_out >= 258 for each loop to avoid checking for
-      available output space while decoding.

-
-/*
- * Change history:
- *
- * 1.2.beta0    24 Nov 2002
- * - First version -- complete rewrite of inflate to simplify code, avoid
- *   creation of window when not needed, minimize use of window when it is
- *   needed, make inffast.c even faster, implement gzip decoding, and to
- *   improve code readability and style over the previous zlib inflate code
- *
- * 1.2.beta1    25 Nov 2002
- * - Use pointers for available input and output checking in inffast.c
- * - Remove input and output counters in inffast.c
- * - Change inffast.c entry and loop from avail_in >= 7 to >= 6
- * - Remove unnecessary second byte pull from length extra in inffast.c
- * - Unroll direct copy to three copies per loop in inffast.c
- *
- * 1.2.beta2    4 Dec 2002
- * - Change external routine names to reduce potential conflicts
- * - Correct filename to inffixed.h for fixed tables in inflate.c
- * - Make hbuf[] unsigned char to match parameter type in inflate.c
- * - Change strm->next_out[-state->offset] to *(strm->next_out - state->offset)
- *   to avoid negation problem on Alphas (64 bit) in inflate.c
- *
- * 1.2.beta3    22 Dec 2002
- * - Add comments on state->bits assertion in inffast.c
- * - Add comments on op field in inftrees.h
- * - Fix bug in reuse of allocated window after inflateReset()
- * - Remove bit fields--back to byte structure for speed
- * - Remove distance extra == 0 check in inflate_fast()--only helps for lengths
- * - Change post-increments to pre-increments in inflate_fast(), PPC biased?
- * - Add compile time option, POSTINC, to use post-increments instead (Intel?)
- * - Make MATCH copy in inflate() much faster for when inflate_fast() not used
- * - Use local copies of stream next and avail values, as well as local bit
- *   buffer and bit count in inflate()--for speed when inflate_fast() not used
- *
- * 1.2.beta4    1 Jan 2003
- * - Split ptr - 257 statements in inflate_table() to avoid compiler warnings
- * - Move a comment on output buffer sizes from inffast.c to inflate.c
- * - Add comments in inffast.c to introduce the inflate_fast() routine
- * - Rearrange window copies in inflate_fast() for speed and simplification
- * - Unroll last copy for window match in inflate_fast()
- * - Use local copies of window variables in inflate_fast() for speed
- * - Pull out common wnext == 0 case for speed in inflate_fast()
- * - Make op and len in inflate_fast() unsigned for consistency
- * - Add FAR to lcode and dcode declarations in inflate_fast()
- * - Simplified bad distance check in inflate_fast()
- * - Added inflateBackInit(), inflateBack(), and inflateBackEnd() in new
- *   source file infback.c to provide a call-back interface to inflate for
- *   programs like gzip and unzip -- uses window as output buffer to avoid
- *   window copying
- *
- * 1.2.beta5    1 Jan 2003
- * - Improved inflateBack() interface to allow the caller to provide initial
- *   input in strm.
- * - Fixed stored blocks bug in inflateBack()
- *
- * 1.2.beta6    4 Jan 2003

-   inflate() uses a state machine to process as much input data and generate as
-   much output data as possible before returning.  The state machine is
-   structured roughly as follows:
-
-    for (;;) switch (state) {
-    ...
-    case STATEn:
-        if (not enough input data or output space to make progress)
-            return;
-        ... make progress ...
-        state = STATEm;
-        break;
-    ...
-    }
-
-   so when inflate() is called again, the same case is attempted again, and
-   if the appropriate resources are provided, the machine proceeds to the
-   next state.  The NEEDBITS() macro is usually the way the state evaluates
-   whether it can proceed or should return.  NEEDBITS() does the return if
-   the requested bits are not available.  The typical use of the BITS macros
-   is:
-
-        NEEDBITS(n);
-        ... do something with BITS(n) ...
-        DROPBITS(n);
-
-   where NEEDBITS(n) either returns from inflate() if there isn't enough
-   input left to load n bits into the accumulator, or it continues.  BITS(n)
-   gives the low n bits in the accumulator.  When done, DROPBITS(n) drops
-   the low n bits off the accumulator.  INITBITS() clears the accumulator
-   and sets the number of available bits to zero.  BYTEBITS() discards just
-   enough bits to put the accumulator on a byte boundary.  After BYTEBITS()
-   and a NEEDBITS(8), then BITS(8) would return the next byte in the stream.
-
-   NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return
-   if there is no input available.  The decoding of variable length codes uses
-   PULLBYTE() directly in order to pull just enough bytes to decode the next
-   code, and no more.
-
-   Some states loop until they get enough input, making sure that enough
-   state information is maintained to continue the loop where it left off
-   if NEEDBITS() returns in the loop.  For example, want, need, and keep
-   would all have to actually be part of the saved state in case NEEDBITS()
-   returns:
-
-    case STATEw:
-        while (want < need) {
-            NEEDBITS(n);
-            keep[want++] = BITS(n);
-            DROPBITS(n);
-        }
-        state = STATEx;
-    case STATEx:
-
-   As shown above, if the next state is also the next case, then the break
-   is omitted.
-
-   A state may also return if there is not enough output space available to
-   complete that state.  Those states are copying stored data, writing a
-   literal byte, and copying a matching string.
-
-   When returning, a "goto inf_leave" is used to update the total counters,
-   update the check value, and determine whether any progress has been made
-   during that inflate() call in order to return the proper return code.
-   Progress is defined as a change in either strm->avail_in or strm->avail_out.
-   When there is a window, goto inf_leave will update the window with the last
-   output written.  If a goto inf_leave occurs in the middle of decompression
-   and there is no window currently, goto inf_leave will create one and copy
-   output to the window for the next call of inflate().
-
-   In this implementation, the flush parameter of inflate() only affects the
-   return code (per zlib.h).  inflate() always writes as much as possible to
-   strm->next_out, given the space available and the provided input--the effect
-   documented in zlib.h of Z_SYNC_FLUSH.  Furthermore, inflate() always defers
-   the allocation of and copying into a sliding window until necessary, which
-   provides the effect documented in zlib.h for Z_FINISH when the entire input
-   stream available.  So the only thing the flush parameter actually does is:
-   when flush is set to Z_FINISH, inflate() cannot return Z_OK.  Instead it
-   will return Z_BUF_ERROR if it has not reached the end of the stream.

-   These memory tracking routines are provided to zlib and track all of zlib's
-   allocations and deallocations, check for LIFO operations, keep a current
-   and high water mark of total bytes requested, optionally set a limit on the
-   total memory that can be allocated, and when done check for memory leaks.
-
-   They are used as follows:
-
-   z_stream strm;
-   mem_setup(&strm)         initializes the memory tracking and sets the
-                            zalloc, zfree, and opaque members of strm to use
-                            memory tracking for all zlib operations on strm
-   mem_limit(&strm, limit)  sets a limit on the total bytes requested -- a
-                            request that exceeds this limit will result in an
-                            allocation failure (returns NULL) -- setting the
-                            limit to zero means no limit, which is the default
-                            after mem_setup()
-   mem_used(&strm, "msg")   prints to stderr "msg" and the total bytes used
-   mem_high(&strm, "msg")   prints to stderr "msg" and the high water mark
-   mem_done(&strm, "msg")   ends memory tracking, releases all allocations
-                            for the tracking as well as leaked zlib blocks, if
-                            any.  If there was anything unusual, such as leaked
-                            blocks, non-FIFO frees, or frees of addresses not
-                            allocated, then "msg" and information about the
-                            problem is printed to stderr.  If everything is
-                            normal, nothing is printed. mem_done resets the
-                            strm members to Z_NULL to use the default memory
-                            allocation routines on the next zlib initialization

-  Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:
-  x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.
-
-  Polynomials over GF(2) are represented in binary, one bit per coefficient,
-  with the lowest powers in the most significant bit.  Then adding polynomials
-  is just exclusive-or, and multiplying a polynomial by x is a right shift by
-  one.  If we call the above polynomial p, and represent a byte as the
-  polynomial q, also with the lowest power in the most significant bit (so the
-  byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
-  where a mod b means the remainder after dividing a by b.
-
-  This calculation is done using the shift-register method of multiplying and
-  taking the remainder.  The register is initialized to zero, and for each
-  incoming bit, x^32 is added mod p to the register if the bit is a one (where
-  x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
-  x (which is shifting right by one and adding x^32 mod p if the bit shifted
-  out is a one).  We start with the highest power (least significant bit) of
-  q and repeat for all eight bits of q.
-
-  The first table is simply the CRC of all possible eight bit values.  This is
-  all the information needed to generate CRCs on data a byte at a time for all
-  combinations of CRC register values and incoming bytes.  The remaining tables
-  allow for word-at-a-time CRC calculation for both big-endian and little-
-  endian machines, where a word is four bytes.
