We do this a lot, and had boutique helpers in various places. So add
a more generic one; for convenience it returns a pointer to the new
end element.
I prefer the name tal_arr_expand to tal_arr_append, since it's up to
the caller to populate the new array entry.

tal_count() is used where there's a type, even if it's char or u8, and
tal_bytelen() is going to replace tal_len() for clarity: it's only needed
where a pointer is void.
We shim tal_bytelen() for now.

This requires a tweak to generate-wire.py too, since it always called the
top-level routine 'print_message'.

gossip_getnodes_entry was used by gossipd for reporting nodes, and for
reporting peers. But the local_features field is only available for peers,
and most other fields are only available from node_announcement.
Note that the connectd change actually means we get less information
about peers: gossipd used to do the node lookup for peers and include the
node_announcement information if it had it.
Since generate_wire.py can't create arrays-of-arrays, we add a 'struct
peer_features' to encapsulate the two feature arrays for each peer, and
for convenience we add it to lightningd/gossip_msg.

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,
but better to be explicit.

This is based on @NicolasDorier's excellent proposal for a Dockerfile, sans the
writing of a config file.

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.
Makefile:230: recipe for target 'check-spelling' failed

The close_info is needed to re-derive the secret key that is supposed
to be used to sign the input spending the output.

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.
