253b25522b BOLT: update to version which requires option_channel_htlc_max.
We will now simply reject old-style ones as invalid.  Turns out the
only trace we could find is a channel between two nodes unconnected to
the rest of the network.

Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Changed: Protocol: We now require all channel_update messages include htlc_maximum_msat (as per latest BOLTs)

6338758018 gossmap: make API more robust against future changes.
Many changes to gossmap (including the pending ones!) don't actually
concern readers, as long as they obey certain rules:

1. Ignore unknown messages.
2. Treat all 16 upper bits of length as flags, ignore unknown ones.

So now we split the version byte into MAJOR and MINOR, and you can
ignore MINOR changes.

We don't expose the internal version (for creating the map)
programmatically: you should really hardcode what major version you
understand!

a770f51d0e tools/generate_wire.py: make functions allocate the TLV.
Requiring the caller to allocate them is ugly, and differs from
other types.

This means we need a context arg if we don't have one already.

4ffda340d3 check: make sure all files outside contrib/ include "config.h" first.
And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).

config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.

c34c055d82 Makefile: use completely separate spec-derived files for EXPERIMENTAL_FEATURES
This avoids overwriting the ones in git, and generally makes things neater.

We have convenience headers wire/peer_wire.h and wire/onion_wire.h to
avoid most #ifdefs: simply include those.

0d2a4830ed ccan: update to faster and correct crc32c implementation.
I decided to try a faster implementation, only to find our crc32c was
not correct!  Ouch.

I removed the crc32c functions from ccan/crc, and added a new crc32c
module which has the Mark Adler x86-64-optimized variants.

We bump gossip_store version again, since csums have changed.

7ede5aac31 gossip_store: change format so we store raw messages.
Save some overhead, plus gets us ready for giving subdaemons direct
store access.  This is the first time we *upgrade* the gossip_store,
rather than just discarding.

The downside is that we need to add an extra message after each
channel_announcement, containing the channel capacity.

78ef30b5ff devtools/create-gossipstore: fix false cppcheck warning.
[devtools/create-gossipstore.c:153]: (error) Uninitialized variable: scidsats

scidsats access is gated by csvfile, which means this warning is a false
positive.  However, it's cleaner to gate scidsts on itself, rather than
the cmdline option which caused it to be populated, so do that.
