Implement AEAD-ChaCha20-Poly1305.

Browse Source 
This implementation is based off the description in RFC 7539.

The ChaCha20 code is also updated to provide a means of generating
keystream blocks with arbitrary counter values. This is used to
generated the one-time Poly1305 key in the AEAD construction.
