For message read, we do it as header then body, so we can have
io_plan_in_started(conn) false, but we're between header and body.

In particular, the main daemon needs to pass it about (marshal/unmarshal)
but it won't need to actually use it after the next patch.

We alternated between using a sha256 and using a privkey, but there are
numerous places where we have a random 32 bytes which are neither.
This fixes many of them (plus, struct privkey is now defined in terms of
struct secret).

Raw crypto_state is what we send across the wire: the peer one is for
use in async crypto io routines (peer_read_message/peer_write_message).

wire_sync_write() adds length, but we already have it, so use write_all.
sync_crypto_read() handed an on-stack buffer to cryptomsg_decrypt_header,
which expected a tal() pointer, so use the known length instead.
sync_crypto_read() also failed to read the tag; add that in (no
overflow possible as 16 is an int, len is a u16).

It's awkward to handle them differently. But this change means we
need to expose them to the generated code.
