8c665835fa jsonrpc: make explicit call to indicate cmd is still pending.
jsonrpc handlers usually directly call command_success or
command_fail; not doing that implies they're waiting for something
async.

Put an explicit call (currently a noop) there, and add debugging
checks to make sure it's used.

2988e290cf gossip: Added internal gossip message to add a local channel
Couldn't find a good place to put these messages, we probably want to
do the same capability based request routing that we did for the HSM,
but for now this just defines the message in the master messages file.

477a529856 pay: make sure we don't think payment in progress if it immediately fails.
If send_htlc_out() fails, it doesn't initialize pc->out; that can
make us think it's still in progress.

94711969f9 gossipd: hand out gossip_index to other daemons.
When gossipd sends a message, have a gossip_index.  When it gets back a
peer, the current gossip_index is included, so it can know exactly where
it's up to.

Most of this is mechanical plumbing through openingd, channeld and closingd,
even though openingd and closingd don't (currently) read gossip, so their
gossip_index will be unchanged.

67aa95c194 gossipd: hand back peer, don't hand a new peer.
All peers come from gossipd, and maintain an fd to talk to it.  Sometimes
we hand the peer back, but to avoid a race, we always recreated it.

The race was that a daemon closed the gossip_fd, which made gossipd
forget the peer, then master handed the peer back to gossipd.  We stop
the race by never closing the gossipfd, but hand it back to gossipd
for closing.

Now gossipd has to accept two fds, but the handling of peers is far
clearer.

899bf3fde9 subd: add transaction to subd exit corner case.
As demonstrated in the test at the end of this series, openingd dying
spontaneously causes the conn to be freed which causes the subd to be

The master now hands channeld either an error code, and channeld
generates the error message, or an error message relayed from another
node to pass through.

to give us that.

This is mainly used to filter for transactions that may be of interest
to us, i.e., whether one of our keys is the recipient. It currently
does onyl simple scriptpubkey checks, but will eventually be extended
to use bloomfilters and add more sophisticated checks.

For now the goal is to speed up the processing of blocks during startup.

79443d6f94 htlc: Defer saving the outgoing payment until we store the HTLC
This addresses a performance regression introduced by
6ceb375650. We were storing it in an
otherwise empty DB transaction, which means that DB transaction was no
longer a no-op. Now we defer storing until we need to store the
corresponding HTLC anyway, so we can just piggyback on top of that
transaction.

This is also more consistent since we'd be forgetting the payment
anyway if we restart between adding the HTLC and committing to it.
