Add a few special case digests not returned by FIPS_get_digestbynid().

Thanks to Roumen Petrov <openssl@roumenpetrov.info> for reporting this
issue.

Although the memory allocated by compression methods is fixed and
cannot grow over time it can cause warnings in some leak checking
tools. The function SSL_COMP_free_compression_methods() will free
and zero the list of supported compression methods. This should
*only* be called in a single threaded context when an application
is shutting down to avoid interfering with existing contexts
attempting to look up compression methods.

Add option to set an alternative to the default hmacWithSHA1 PRF
for PKCS#8 private key encryptions. This is used automatically
by PKCS8_encrypt if the nid specified is a PRF.

Add option to pkcs8 utility.

Update docs.

Don't set the fips flags in cipher and digests as the implementations
aren't suitable for FIPS mode and will be redirected to the FIPS module
versions anyway.

Return EVP_CIPH_FLAG_FIPS or EVP_MD_FLAG_FIPS if a FIPS implementation
exists when calling EVP_CIPHER_flags and EVP_MD_flags repectively.

Remove unused FIPS code from e_aes.c: the 1.0.2 branch will never be
used to build a FIPS module.

The file evp_fips.c isn't used in OpenSSL 1.0.2 as FIPS and non-FIPS
implementations of algorithms can coexist.

Not all platforms define BN_ULLONG. Define SCTS_TIMESTAMP as a type
which should work on all platforms.

Windows 8 SDKs complain that GetVersion() is deprecated.

We only use GetVersion like this:

	(GetVersion() < 0x80000000)

which checks if the Windows version is NT based. Use a macro check_winnt()
which uses GetVersion() on older SDK versions and true otherwise.
