Nettle: Moved GCM to a Cipher submodule.
The various tastes of GCM now follow the AEAD API properly.
Crypto.GCM is no more, instead there are Crypto.AES.GCM,
Also updates the SSL code accordingly.
__builtin.Nettle: Added __Hash and MAC.
This moves the base hash API to __Hash, and adds a common
API for Message Authentication Codes (MACs) analogous to
the APIs for hashes and ciphers.
Merge branch '8.0' into gobject-introspection
Crypto.ECC: Document the constant curves as modules.
As these values are intended to be treated as modules,
document them as such.
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.
Crypto.ECC: Added some Elliptic Curve Crypto support.
Nettle & SSL: Fixed a few Autodoc markup typos.
Nettle.GCM: Now follows the same conventions as other ciphers.
Also adds a new base class for AEAD ciphers: __builtin.Nettle.AEAD.
Nettle: Fixed some broken Autodoc markup.
Also fixes an Autodoc typo in udp.c.
Nettle.GCM is not always available.
Nettle: Added Galois Counter Mode (GCM)
