983000428f daemon: rename CMD_SEND_HTLC_UPDATE to CMD_SEND_HTLC_ADD 
There are other updates than just adding an HTLC; make this explicit.

a2f4000d22 state: cleanup after anchor has been transmitted. 
If something goes wrong after we've broadcast the anchor tx, we need to use
the commit tx to spend it.

79e1c9bb62 state: make bitcoin_commit() take a non-const peer. 
We have to sign the commit at this stage, so easiest if peer isn't const
so we can sign it in-place.

6a7a046f60 state: add peer_unwatch_close_timeout() call.

ebf2bc57d8 state: add async anchor creation. 
Actually generating the anchor transaction in my implementation
requires interaction with bitcoind, which we want to be async.  So add
a callback and a new state to wait for it.

63cb0667f6 state: use callbacks for htlc management. 
We only have one htlc in flight at a time, but sometimes it changes:
particularly when we are lowpriority and a highpriority request comes
in.  Handle this using a set of callbacks for htlc handling.

fd370075f2 state: use STATE_INIT and separate inputs to decide on anchor.

special case needed).
