aead/{,x}chacha20-poly1305: simplify
...
Use one-pass interfaces for encryption and decryption and rename the
Poly1305 key setup to the more correct poly1305_keysetup.

aead/chacha20-poly1305: inline anycrypt
...
Also use decrypt for the decryption path instead of relying on ChaCha20
using the same stream for encryption and decryption.

aead: replace init args with implementation-specific params struct
...
This unbreaks {,X}ChaCha20-Poly1305. Thanks to the use of params, the
{,X}ChaCha20-Poly1305 doesn't need to reach into the guts of ChaCha20
state. Move {en,de}cryption and key setup into its own functions.
This breaks the tests, which will be fixed in the following commit.
