Changed many tests so they also test fips (and removed 'availablein = default' from some tests). Seperated the monolithic evppkey.txt file into smaller maintainable groups. Changed the availablein option so it must be first - this then skips the entire test before any fetching happens. Changed the code so that all the OPENSSL_NO_XXXX tests are done in code via methods such as is_cipher_disabled(alg), before the fetch happens. Added missing libctx's found by adding a libctx to test_evp. Broke up large data files for cipher, kdf's and mac's into smaller pieces so they no longer need 'AvailableIn = default' Added missing algorithm aliases for cipher/digests to the providers.
