Remove ctx_new and ctx_free function pointers
...
Now that HMAC isn't special anymore, and with the help of init params,
this isn't needed anymore as we only allocate memory for the state.

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.
