I implemented this because a bug causes us to consider the HTLC malformed,
so I can trivially test it for now.

Since we now use the short_channel_id to identify the next hop we need
to resolve the channel_id to the pubkey of the next hop. This is done
by calling out to `gossipd` and stuffing the necessary information
into `htlc_end` and recovering it from there once we receive a reply.
This was overly complex since it was off-by-one and we were storing
some information elsewhere. Now this just loads the route as is into
structs, extracts some information for our outgoing HTLC, and then
shifts by the array of structs by one, and finally fills in the last
instruction, which is the terminal.
The new onion uses the `channel_id` instead of the `node_id` of the
next hop to identify where to forward the payment. So we return the
exact channel chosen by the routing algo, to avoid having to look it
up again later.
Mainly switching from the old include to the new include and adjusting
the actual size of the onion packet. It also moves `channel.c` to use
`struct hop_data`.
It introduces a dummy next hop in `channel.c` that will be replaced in
the next commit.
Adds a new command line flag `--dev-broadcast-interval=<ms>` that
allows us to specify how often the staggered broadcast should
trigger. The value is passed down to `gossipd` via an init message.
This is mainly useful for integration tests, since we do not want to
wait forever for gossip to propagate.
We were using an uninitialized `broadcast_index` on the peer which
would occasionally result in no forwardings at all, segmenting the
network. And during the `msg_queue` refactor, some wait targets were
not updated, resulting in the waits never to be woken up.
This moves all the non-legacy blackbox testing into python.

Note that this doesn't valgrind the subdaemons: that patch seems to cause
some issues in the python framework which I am still chasing.

The Dockerfile is now stored in contrib and built using the Docker
Hub. This allows us to simply pull in the finished image from the hub
instead of having to build it ourself. Should shave off about 2
minutes from the build time.
I also switched to running the individual build and check steps in
their own containers, but on the same volume, so travis can group the
commands and run them independently.
Running long integration tests could result in `bitcoind` dropping the
connection inbetween calls, and since python-bitcoinlib does not
reconnect and/or retry, all subsequent tests would fail as well. This
patch switches to throwaway connections, each serving just one
request. It's easier than to reach into the bitcoinlib to reconnect
and reauth, but comes with some overhead, but I think it's acceptable
for the few bitcoin calls we actually perform.
We seem to be getting spurious reconnect failures on Travis, this
should fix it (15 seconds may be too long at worst case).

Rather than dumping all gossip messages then handling local ones again.
This should help us give timely ping replies.

The callback on `key_negotiate` was closing the connection under
certain circumstances and would also `free` the key_negotiate, which
would then be freed again once it returns. We steal it off of the
connection during the callback and doing the free manually afterwards
to make sure this can't happen.
Thanks to @jgriffiths for tracking this one down.

This fails on the old dev-restart tests, so we need to only enable it
for the new tests:

...
{ }
RESTARTING
dev-restart failed!

valgrind: this can be caused by executables with very large text, data or bss segments.

Only the side *accepting* the connection gives a `minumum_depth`, but both
sides are supposed to wait that long:
BOLT #2:
### The `funding_locked` message
...
#### Requirements
The sender MUST wait until the funding transaction has reached
`minimum-depth` before sending this message.
