** libgnutls: Added --enable-fips140-mode configuration option. That
option enables (when running on FIPS140-enabled system):
o DSA and DH key generation as in FIPS-186-4 (using provable primes)
- o The DRBG-AES deterministic random generator from ANSI X9.31
- Appendix A.2.4.
+ o The DRBG-CTR-AES256 deterministic random generator from SP800-90A.
o Self-tests on initialization on ciphers/MACs, public key algorithms
and the random generator.
o HMAC-SHA256 verification of the library on load.
