Well, it's generated by shachain, so technically it is a sha256, but
that's an internal detail. It's a secret.

We already work around this by using an array with a 0/1 length convention,

If we change an upstream URL, all submodules break. Users would need
to run 'git submodule sync'. Note that the libbacktrace fix was merged
upstream so this is no longer necessary, but it's good for future changes.
Also, stress-testing reveals that git submodule fails locking
'.git/config' when run in paralell. It also segfaults and other
problems.
This is my final attempt to fix submodules; I've wasted far too many
days on obscure problems it creates: I've already lost one copy of my
repo to apparently unfixable submodule preoblems. The next "fix" will
be to simply import the source code so it works properly.

We were using `\x0` to match NUL chars in the input (on the
assumption that NUL chars are "impossible" for decent LFS-compliant
systems).
However `\x0` is a GNUism.
Use the `\n` and the newline character, which is supported by (most)
POSIX sed.
We always hand in "NULL" (which means use tal_len on the msg), except
for two places which do that manually for no good reason.

A convenient alias for char *, though we don't allow control characters
so our logs can't be fooled with embedded \n.

These are now logically arrays of pointers. This is much more natural,
and gets rid of the horrible utxo array converters.

The pagination causes it to wait for a keypress even with no output
under emacs (complaining about the terminal); we don't want it anyway.
Example output:
Makefile:228:#lighnting!
Identified a likely misspelling of the word "lightning" (see above). Please fix.
Is this warning incorrect? Please teach tools/check-spelling.sh about the exciting new word.

It's just a sha256_double, but importantly when we convert it to a
string (in type_to_string, which is used in logging) we use
bitcoin_blkid_to_hex() so it's reversed as people expect.

If a structure foo has a optional fields opt1 and opt2, this creates
towire_foo, towire_foo_opt1 and towire_foo_opt2 (since opt2 implies opt1),
similarly for fromwire_*.
This requires the callers to be updated to call the correct routines (eg.
try fromwire_foo_opt2, then fromwire_foo_opt1, then finally fromwire_foo),
but this is a minimal change to the generation code.

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).

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).

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

It implies tal_count() gives the length. Great for almost all callers which

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.
