keyset: abstraction over what keys we need for a specific commitment.
onchaind will need to do similar logic to channeld, so this allows them

lightningd: --dev-disconnect support.
We use a file descriptor, so when we consume an entry, we move past it
(and everyone shares a file offset, so this works).
The file contains packet names prefixed by - (treat fd as closed when
we try to write this packet), + (write the packet then ensure the file
descriptor fails), or @ ("lose" the packet then ensure the file
descriptor fails).
The sync and async peer-write functions hook this in automatically.

lightningd/peer_control: don't create peer struct until we've connected.
We currently create a peer struct, then complete handshake to find out
who it is. This means we have a half-formed peer, and worse: if it's
a reconnect we get two peers the same.
Add an explicit 'struct connection' for the handshake phase, and
construct a 'struct peer' once that's done.

lightningd/subd: new code for subdaemons.
This uses a single fd for both status and control.
To make this work, we enforce the convention that replies are the same
as requests + 100, and that their name ends in "_REPLY".
This also means that various daemons can simply exit when done; there's
no race between reading request and closing status fds.
