Crypto.DSA: Moved some functions from Standards.PKCS.DSA.
To avoid circular dependencies between Crypto.DSA and
Standards.PKCS.DSA the pkcs_*() functions are now
inlined in Crypto.DSA.
This also adds pkcs_algorithm_identifer() to Crypto.DSA.
Fixes module dumping problems for Crypto.DSA.
Crypto.RSA: pkcs_algorithm_id() ==> pkcs_signature_algorithm_id()
Renamed the function above in Crypto.RSA and Crypto.DSA to
avoid confusion with the similar algorithm_identifier().
Merge branch '8.0' into gobject-introspection
SSL.Cipher: Improved TLS 1.2 compatibility.
The TLS 1.2 prf is now derived from the hash function used for
the MAC for the suite, as this seems to be the convention for
all the suites that have been defined after TLS 1.2.
This simplifies implementation of the prf selection behaviour
specified eg for the suites defined in RFC 6367 3.3:
When used with TLS versions prior to 1.2 (TLS 1.0 and TLS 1.1),
the PRF is calculated as specified in the appropriate version
of the TLS specification.
Restructured RSA and DSA so that they resemble each other in structure
RSA->query_blocksize (now block_size)
RSA->rsa_size (now key_size)
