configure.ac:

* in handling for enable-all-asm, add check for full Gnu C and don't auto-enable all-asm unless full Gnu C and enable-all-crypto, among other sanity checks.
* in enable-all and enable-all-crypto, correctly conditionalize several FIPS-v6-only features/algorithms.
* in FIPS v5 setup, force off SRTP and SRTP-KDF (with warnings).
