103ac79c34 lightningd: expose channel in getpeers.
Lets us manually construct routes, for testing, and replaces the 'locked'
flag as well.

09e489030c channeld: implement malformed HTLC message.
I implemented this because a bug causes us to consider the HTLC malformed,
so I can trivially test it for now.

39115717f6 channeld: Passing additional info to channeld

25f1cba3cf routing: Ask gossipd to resolve channel_id and forward HTLCs
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.

b9dcb909b8 routing: Simplify code to read the route back in
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.

d87ca4121d routing: Returning channel_id to getroute requests
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.

f24aab1916 sphinx: Updating daemon to new sphinx implementation
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.

b4beab6537 gossip: Make the broadcast interval configurable
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.

4bc6ee1088 gossip: Fix two bugs in the forwarding of gossip
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.

f61da7eb64 tests/test_lightningd.py: incorporate everything from old test-basic shell test.
This moves all the non-legacy blackbox testing into python.

Before:

After:

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