Make params struct non-const
...
Upcoming changes will push lc_*_ctx into the params struct for higher
order constructions like HMAC or HKDF.

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.

cipher/chacha20: buffer the full input block

The final implementation is simpler, at the cost of doing work in
chacha20_x_final.

Fix *_ctx_new and *_ctx_free implementations
...
They both will only alloc and free the internal *_ctx structs. Get rid
of the void * argument for new and only pass arg to *_free instead of
the whole lc_*_ctx struct.
