Now in sync with 8ee57b97738b1e9467a1342ca8373d40f0c4aca5.
Our tool doesn't need to convert them any more, but we actually had a
mis-typed field in the HSM which needed fixing.

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.
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.
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.

Except for the trivial case of u8 arrays, have the generator create
the loop code for the array iteration.
This removes some trivial helpers, and avoids us having to write more.

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.
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.

It's awkward to handle them differently. But this change means we
need to expose them to the generated code.

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'.

For our internal CSV files, we can specify the type explicitly rather
than trying to guess (eg. bool).

Pretty! Takes an int instead of the enum directly, because in the
main daemon we call it via a function pointer, so want them all the
same type.

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.

We emit them into the generated code at appropriate points, but it
would be better if we simply preserved the order they were given in.

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.
