We will want to use it in the pay plugin too.

9450d46db1 bitcoin/short_channel_id: pass by copy everywhere.
It's a u64, we should pass by copy.  This is a big sweeping change,
but mainly mechanical (change one, compile, fix breakage, repeat).

0274d88bad common/gossip_store: clean up header.
It's actually two separate u16 fields, so actually treat it as
such!

Cleans up zombie handling code a bit too.

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.

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!

572942c783 psbt: use DER encoded + sighash byte for PSBT_IN_PARTIAL_SIG items
Per BIP-0171, the signature map is of pubkey to "The signature as would
be pushed to the stack from a scriptSig or witness".

Fixes 5298

116a77f1be lightningd: Restore forwarding of legacy onions.
Partial revert of 43a833e405
"lightningd: remove support for legacy onion format."; we restore the
ability to decode legacy onions for forwarding, but not to generate them.
(We don't accept them properly since making payment_secret compulsory
anyway, so no real change there!)

Changelog-Removed: Protocol: ... but we still forward legacy HTLC onions for now.

83ee68ab06 common/tlvstream: put TLV checking back in the generic function.
Callers were supposed to call "tlv_fields_valid" after fromwire_tlv,
but few did.  Make this the default, and call the underlying function
directly where we want to be more flexible (one place).

This loses the ability to allow misordered fields, or to pass through
*any* even fields.  We restore that for special cases in the next
patch.

35e3c1866e common: generalize extract_channel_id().
connectd is going to end up using this do demux; make it fast and complete.

Fixing this reveals a problem in openingd: it now extracts the channel_id
from funding_signed (which is where we transition off the temporary), and
gets upset.  So fix that.

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.

1f79aad830 common/utils: introduce tmpdir_mkstemp; use it
Various unit tests were creating temporary files unconditionally in /tmp
and were not cleaning up after themselves. Introduce a new variant of
mkstemp(3p) that respects the TMPDIR environment variable, and use it in
the offending unit tests. This allows each test run to use a dedicated
TMPDIR that can be cleaned up after the run.

cb22015b2a common/channel_type: wrapper for generated 'struct channel_type'.
We make it a first-class citizen internally, even though we won't use
it over the wire (at least, non-experimental builds).  This scheme
follows the latest draft, in which features are flagged compulsory.

We also add several helper functions.

Since uses the *even* bits (as per latest spec), not the *odd* bits,
we have some other fixups.
