This will be used to decouple internal use of gossip from what is
passed to gossip peers. Updates GOSSIP_STORE_VERION to 10.
Changelog-Changed: gossip_store updated to version 10.
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.
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.

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.

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.

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.

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.

This takes an extra 8 bytes per channel, but means we can go back and
get more information about them; this is implemented in
gossmap_chan_get_update_details() which is what listchannels will need.

This was likely missed because we don't run the tests under valgrind anymore
due to time constraints. I do run them on a semi-regular basis, which is why
I found this.
Now we create a separate set of local mods, and apply and unapply it.
This is more efficient than the previous approach, since we can do
some work up-front. It's also more graceful (and well-defined) when a
local modification overlaps an existing one.
