ee1fb07c8e update-mocks: fix stubs generation for fatal().
We're going to need this, and the PRINTF_FMT(1,2) in front of it caused
mockup.sh to miss the declaration.

We also eliminate the obviously-unused fallback case (which referred
to daemon/*.h).

8a829ba9cb update-mocks: move mock generation into tools/, fix and generalize.
update-mocks was broken, since it assumed the daemon/ directory.

We now use "make" directly to build the test file and harvest errors,
and are more robust if it simply doesn't compile (ie. fails, but no
linker errors).

67315be673 travis: Simplified build script
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.

b2ea4cfd66 wiregen: Passing ctx to array helpers that require it
Some of the struct array helpers need to allocate data when
deserializing their fields. The `getnodes` reply is one such example
that allocates the hostname. Since the change to calling array helpers
the getnodes call was broken because it was attempting to allocate off
of the entry, which did not have a tal header, thus failing.

e042198cf8 tools/generate-wire.py: allow typename instead of type sizes.
We use the fourth value (size) to determine the type, unless the fifth
value is suppled.  That's silly: allow the fourth value to be a typename,
since that's the only reason we care about the size at all!

Unfortunately there are places in the spec where we use a raw fieldname
without '*1' for a length, so we have to distingish this from the
typename case.

4a995a42de gen-wire: Cleanup of the wire generator tool
The wiregen tool was a bit hard to maintain since it was printing all
over the place, mixing template and processing logic. This commit
tears the two apart, externalizes everything that is not a single code
line, and repackages it into templates. Specifically functions are now
their own template and header/implementation files are a template.

Furthermore this simplifies some of the boilerplate of mapping types
to sizes and back again, by extracting them into dicts.

All changes have been verified to produce identical results on the
current wire definitions, except a bit of whitespace changes.

7419fde9a0 Update to new spec: differentiate channel_id and short_channel_id.
The spec 4af8e1841151f0c6e8151979d6c89d11839b2f65 uses a 32-byte 'channel-id'
field, not to be confused with the 8-byte short ID used by gossip.  Rename
appropriately, and update to the new handshake protocol.

8b72604d4d wire: allow #include directives in csv comments, and unknown structure types.
This lets us marshal and unmarshal undefined complex types; the fromwire
function will allocate it for us, so we don't even need to know the size.

This turns out to be really nice for marshalling 'struct crypto_state'.
