[pycrypto] SHA-224, SHA-384 and SHA-512 Implementations

[Lorenz Quack]

Hi,

I just posted a patch series implementing the missing SHA-2 family Hashes.
Namely: SHA-224, SHA-384 and SHA-512
If anyone is interested please try them out and let me know if there are any problems.
I also included test cases in lib/Crypto/SelfTest/Hash

The patches can be found here: https://bugs.launchpad.net/pycrypto/+bug/544792

The main caveat is the way I check for fixed size data types like uint32_t and uint64_t
in src/hash_SHA2.h.
If anybody knows a good way to do this please let me know.

Sincerely yours,
//Lorenz
