This was the only time we actually reference non-routing structs in
routing, so moving this out should allow us to get it working in the
new subdaemons.
This allows us to move some legacy functions closer to where they are
actually used, and not worry about them when including routing.h into
the new subdaemons. `struct peer` is the main culprit here.
This used to be part of `lightningd_state` which is being split up for
the various subdaemons. The main change is the addition of the `struct
routing_state` in `routing.h` and the addition of `rstate` in `struct
lightningd_state` for backwards compatibility.
We had a hack for 'struct rval' in protobuf_convert.h; make an
explicit header and put it in bitcoin/preimage.h. It's not really
bitcoin-specific, but it's better than having bitcoin/script depend on
an external header.

In particular, 860990fa0afb55f839e882a5e9abe8abe6ccb981 reordered
channel_announcement and c93bf5cf8c48eab1b028e85214cb35feeeffcbb3
reordered the update_fail_malformed_htlc message.

This is needed for the new testing framework since we wait for
messages to be printed on stdout. Buffering delays this
arbitrarily. Flushing so often should not have much of a performance
impact.
`awaitinvoice` can be used to wait on a specific invoice to be
completed. If the invoice was previously paid, then the command
returns immediately, otherwise it'll block until the invoice is
paid. This complements `waitinvoice` which uses a highwatermark and
waits for the next invoice. I found waitinvoice a bit hard to use
since it doesn't allow waiting for a specific invoice to be completed,
just the next in the insertion order.
So far this was simply set to a zero-length end-to-end payload. We
don't have any plans of re-adding it for the moment, so let's get rid
of the unused code.
The spec says that we use the libsecp256k1 style ECDH, which uses the
full compressed pubkey from the scalar multiplication which is then
hashed. This is in contrast to the btcsuite implementation which was
only using the hashed X-coordinate.
The API formalizes how daemons should report their statuses back to
the main lightningd. It's a simple write API, which includes tracing
support (currently it always sends traces, later it could send iff
there's a failure, for example).

Before we had a global secp256k1_ctx we needed to hold this to print
out pubkeys, now it's completely orthogonal.

So far it was failing silently, now it diffs the Makefile state
against the directory listing. This also fixes a bug when the locale
was not set the sort order would not match.

new address format for node_announcement.

It implies tal_count() gives the length. Great for almost all callers which
don't care if there are extra bytes.

This removes some redundancy in creating messages, but also allows
a lazy form or parsing without explicitly checking the type.
A helper fromwire_peektype() is added to look up the type and handle
the too-short-for-type problem.

This is a bit more awkward for large structures, but avoids
indirection for the simpler ones (I copied the structures for the test
code, however). We also remove explicit padding.

Other than being neater (no more global list to edit!), this lets the
new daemon and old daemon have their own separate routines.

Keeping a pointer to the peer that initially sent us a message
could (actually will!) result in dangling pointers. Removing this
results in some additional messages, which will be discarded by the
recipient, so that should not be a problem.
Connections are in a half-open state after receiving the
`channel_announcement` and before the `channel_update` makes them
usable, so we need to ignore channels that are not yet fully open.
The gossip protocol spec refers to channels by their `channel_id` and
a direction. Furthermore, inbetween the `channel_announcement` and the
`channel_update` for either direction, the channel direction is in an
undefined state and cannot be used, so added the `half_add_connection`
function and an `active` flag to differentiate usable connections from
unusable ones.
When we support the Milan protocol, we'll use a default port. But
for now, don't listen at all unless a port is specified.

Our HMACs are truncated to 20 byte, but sodium still generates 32 byte
HMACs and we were handing in a buffer that was too small, so we
overflowing the buffer by 12 bytes. This manifested itself only in the
32 bit variant because of different alignment in the 64bit version.
Fixes#94.

Added .travis.yml to get travis-ci to build and run tests for us.
In addition this fixes a flaky test due to the fact that when lightning2
connects to lightning3 and we tell lightning3 to restart, then
lightning2 will back-off its reconnection attempts, potentially causing
a timeout to trigger during tests. This was triggered by travis-ci
relatively consistently since the restart would take quite some
time. Now simply restarting them in reverse order and a small timeout
seems to fix this consistently.
When initially reading the blockchain, we start 100 back from the
current block, or at the first block with a funding transaction,
whichever is earlier.
This slows testing slightly, so use whatever the "forever" value is
(10 on testnet, still 100 on mainnet).

This significantly reduces re-testing of the same paths, and simplifies
the addition of new tests.
