libcrypto fully implemented

Implemented working versions of the following functions for libcrypto:
 sss_base64_encode
 sss_base64_decode
 sss_hmac_sha1
 sss_password_encrypt
 sss_password_decrypt

test_encrypt_decrypt now expects EOK from libcrypto.
test_hmac_sha1 now expects EOK from libcrypto.
Added test_base64_encode to test base64 encoding implementation.
Added test_base64_decode to test base64 decoding implementation.
