Implement FIPS CMAC.

* fips/cmac/*: Implement the basis for FIPS CMAC, using FIPS HMAC as
  an example.
* crypto/cmac/cmac.c: Enable the FIPS API.  Change to use M_EVP macros
  where possible.
* crypto/evp/evp.h: (some of the macros get added with this change)
* fips/fips.h, fips/utl/fips_enc.c: Add a few needed functions and use
  macros to have cmac.c use these functions.
* Makefile.org, fips/Makefile, fips/fips.c: Hook it in.
