Large speedups to Hc-family and Sosemanuk stream ciphers and Poly1305 MAC through use of highly optimised 'unsafe' blocks :) . Smaller, but still significant improvements to the Salsa20 stream cipher and derivatives, XSalsa20 and ChaCha.
Removed CAST 5 and 6 block ciphers, and RC4 stream cipher.
Added Whirlpool MAC back in.
