Fix no-stdio build
Much related/similar work also done by
Ivan Nestlerode <ivan.nestlerode@sonos.com>
+Replace FILE BIO's with dummy ops that fail.
+Include <stdio.h> for sscanf() even with no-stdio (since the declaration
is there). We rely on sscanf() to parse the OPENSSL_ia32cap environment
variable, since it can be larger than a 'long'. And we don't rely on the
availability of strtoull().
+Remove OPENSSL_stderr(); not used.
+Make OPENSSL_showfatal() do nothing (currently without stdio there's
nothing we can do).
+Remove file-based functionality from ssl/. The function
prototypes were already gone, but not the functions themselves.
+Remove unviable conf functionality via SYS_UEFI
+Add fallback definition of BUFSIZ.
+Remove functions taking FILE * from header files.
+Add missing DECLARE_PEM_write_fp_const
+Disable X509_LOOKUP_hash_dir(). X509_LOOKUP_file() was already compiled out,
so remove its prototype.
+Use OPENSSL_showfatal() in CRYPTO_destroy_dynlockid().
+Eliminate SRP_VBASE_init() and supporting functions. Users will need to
build the verifier manually instead.
+Eliminate compiler warning for unused do_pk8pkey_fp().
+Disable TEST_ENG_OPENSSL_PKEY.
+Disable GOST engine as is uses [f]printf all over the place.
+Eliminate compiler warning for unused send_fp_chars().
