* 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.
