Run one travis build with valgrind on legacy tests, off on new daemon
tests, and another build with the roles switched. Should also speed
this up a bit since we run in parallel.
As tracked down by Christian; by setting up the master conn first,
we make the master fd async. This means that the synchronous read
(in init_channel) can fail with -EAGAIN, and indeed, Christian
saw this when not running under valgrind.

We actually don't need to transition if we're reconnecting, and logic
to go to CHANNELD_NORMAL was wrong: we checked that we'd seen funding tx
locked, but not that we'd received a msg from the remote peer.
We need to fix the tests now we no longer double-transition, too.
Fixes: #188

Important: a non-standard one can make the closing tx not propagate.
Drive-by cut&paste message fix, too.

This is what it actually is, and makes it clearer when we refer to the
spec. It's the commitment we're currently updating, which is the next
commitment.

We currently have the problem that the master can send new HTLCs before
we've processed the incoming reestablish message.

The next patch includes wire/peer_wire.h and causes a compile error
as lightningd/gossip_control.c defined its own gossip_msg function.
New names are clearer.

When we drop an HTLC_ADD packet, sometimes the commit timer fires
before we try to read from the fd. In this case, the payment is
considered committed and we don't fail.
We need manual commit to work around this, and also we'd need to do
the pay command asynchronously from python because it will block.
That's a bit out of scope for now, so just handle either way.

This can happen even without a protocol violation, if the incoming
update_add_htlc crosses over our outgoing shutdown.

We keep the scriptpubkey to send until after a commitment_signed (or,
in the corner case, if there's no pending commitment). When we
receive a shutdown from the peer, we pass it up to the master.
It's up to the master not to add any more HTLCs, which works because
we move from CHANNELD_NORMAL to CHANNELD_SHUTTING_DOWN.

We don't need to keep this around any more: by handing it to
subdaemons we ensure we'll close it if the peer disconnects, and we
also add code to get a new one on reconnection.
Because getting a gossip_fd is async, we re-check the peer state after
it gets back. This is kind of annoying: perhaps if we were to hand
the reconnected peer through gossipd (with a flag to immediately
return it) we could get the gossip fd that way and unify the paths?

At the moment, master simply keeps the gossip fd open when peer
disconnects. That's inefficient, and wrong anyway (it may want a
complete new sync, or may not, but we'll currently send all the
messages including stale ones).
This interface will be required for restart anyway.

Now we're always sync, just use an fd. Put the hsm_sync_read() helper
here, too, and do HSM init sync which makes things much simpler.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
With no async calls left, we can just use a stack variable for the fd.
And we're now *always* in the hands of some daemon, unless we're
disconnected, so owner is only NULL in that case.

We had a terrible hack in gossip when a peer didn't exist. Formalize
a pattern when code+200 is a failure (with no fds passed), and use it
here.
