Lucas Gabriel Vuotto a6208487e4 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.
