4db460903a htlc_tx: wire up the htlc points.
All the callers need to pass it in: currently channeld and openingd just
fake it by copying the payment point.

4fb472b7a7 db: we must always be in a transaction, remove nested, call fatal()
We save location where transaction was started, in case we try to nest.
There's now no error case; db_exec_mayfail() is the only one.

This means the tests need to override fatal() if they want to intercept
these errors.

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.

7e022b522c gossipd: don't try to handle padding inside fromwire_ipaddr.
It makes it impossible to embed an ipaddr in another structure, since we
always try to skip over any zeroes, which may swallow a following field.

Do the skip specially for the case where we're parsing routing messages:
we never use padding for our own internal messages anyway.

474887512d gossipd: rewrite to do the handshake internally.
Now the flow is much simpler from a lightningd POV:

1. If we want to connect to a peer, just send gossipd `gossipctl_reach_peer`.
2. Every new peer, gossipd hands up to lightningd, with global/local features
   and the peer fd and a gossip fd using `gossip_peer_connected`
3. If lightningd doesn't want it, it just hands the peerfd and global/local
   features back to gossipd using `gossipctl_handle_peer`
4. If a peer sends a non-gossip msg (eg `open_channel`) the gossipd sends
   it up using `gossip_peer_nongossip`.
5. If lightningd wants to fund a channel, it simply calls `release_channel`.

Notes:
* There's no more "unique_id": we use the peer id.
* For the moment, we don't ask gossipd when we're told to list peers, so
  connected peers without a channel don't appear in the JSON getpeers API.
* We add a `gossipctl_peer_addrhint` for the moment, so you can connect to
  a specific ip/port, but using other sources is a TODO.
* We now (correctly) only give up on reaching a peer after we exchange init
  messages, which changes the test_disconnect case.

5889ad5fc4 dev-disconnect: add blackhole option.
To reproduce the next bug, I had to ensure that one node keeps thinking it's
disconnected, then the other node reconnects, then the first node realizes
it's disconnected.

This code does that, adding a '0' dev-disconnect modifier.  That means
we fork off a process which (due to pipebuf) will accept a little
data, but when the dev_disconnect file is truncated (a hacky, but
effective, signalling mechanism) will exit, as if the socket finally
realized it's not connected any more.

The python tests hang waiting for the daemon to terminate if you leave
the blackhole around; to give a clue as to what's happening in this
case I moved the log dump to before killing the daemon.

40165ba6d5 script: Use pkh to construct p2pkh output scripts
So far we always needed to know the public key, which was not the case
for addresses that we don't own. Moving the hashing outside of the
script construction allows us to send to arbitrary addresses. I also
added the hash computation to the pubkey primitives.

9b1d240c1f lightningd: --dev-disconnect support.
We use a file descriptor, so when we consume an entry, we move past it
(and everyone shares a file offset, so this works).

The file contains packet names prefixed by - (treat fd as closed when
we try to write this packet), + (write the packet then ensure the file
descriptor fails), or @ ("lose" the packet then ensure the file
descriptor fails).

The sync and async peer-write functions hook this in automatically.
