GLEP59: Manifest2 hash types
 
Respun now with the help of ferringb. Cleans up the implementation and catches
a few bug and improvements:
- mhash priority moved lower than pycrypto/hashlib because mhash holds GIL
while the other implementations don't.
- hashlib does offer whirlpool if it was built against openssl 1.0.

1/5: Refactor RMD160 hashlib code for less-hardcoding
2/5: Manifest2 hash: Whirlpool
3/5: Manifest2 hash: SHA512
4/5: Manifest2 hash backend provider: mhash
5/5: GLEP59: Change live Manifest2 hashes to SHA256,

This is released in portage-2.1.10.21 and 2.2.0_alpha61, so please go
ahead and test the "manifest-hashes = SHA256 SHA512 WHIRLPOOL" setting
in metadata/layout.conf, which we can deploy after
>=sys-apps/portage-2.1.10.21 is stable.

Works here in a local copy of metadata/layout.conf.
