core-lightning/lightningd/peer_htlcs.h
Rusty Russell c4f2ada2ff lightningd: split up peer_htlcs a little, create forwards.c
peer_htlcs has become a bit of a dumping ground: move listforwards
etc to its own file.

Also move `struct channel_info` from peer_htlcs.h to channel.h where
it more logically belongs.
