85f065a6e7 peer_control: close leak in sign_last_tx.
We can call this multiple times.  The best solution is to add and remove
the signature so it's always unsigned as we expect it.

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.

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.

3c6eec87e3 Add DEVELOPER flag, set by default.
This is a bit messier than I'd like, but we want to clearly remove all
dev code (not just have it uncalled), so we remove fields and functions
altogether rather than stub them out.  This means we put #ifdefs in callers
in some places, but at least it's explicit.

We still run tests, but only a subset, and we run with NO_VALGRIND under
Travis to avoid increasing test times too much.
