MGF1 digest and OAEP label.
[Steve Henson]
*) Add callbacks supporting generation and retrieval of supplemental
data entries.
[Scott Deboy <sdeboy@apache.org>, Trevor Perrin and Ben Laurie]
*) Add EVP support for key wrapping algorithms, to avoid problems with
existing code the flag EVP_CIPHER_CTX_WRAP_ALLOW has to be set in
the EVP_CIPHER_CTX or an error is returned. Add AES and DES3 wrap

*) Support for linux-x32, ILP32 environment in x86_64 framework.
[Andy Polyakov]
*) RFC 5878 (TLS Authorization Extensions) support.
[Emilia Kasper, Adam Langley, Ben Laurie (Google)]
*) Experimental multi-implementation support for FIPS capable OpenSSL.
When in FIPS mode the approved implementations are used as normal,
when not in FIPS mode the internal unapproved versions are used instead.
