cipher: replace init args with a implementation-specific params struct
...
This allows for more flexibility in the future. While at it, do note
that the RFC and draft implementations are followed. In particular, in
XChaCha20, hardcode the high word of the counter to 0.
This commit breaks ChaCha20-Poly1305. It'll be fixed in a subsequent
commit.
