We don't actually set desired_type yet, but this handles it.
Changelog-EXPERIMENTAL: Protocol: we can now upgrade old channels to `option_static_remotekey` from https://github.com/lightningnetwork/lightning-rfc/pull/868

For quiescence, we can't have sent any updates at all.
But for upgrades on reconnection, we may have already added
uncommitted HTLCs for retransmission, but they don't count towards
"are we quiesced" since they're not sent yet.

This includes anysegwit and the updated HTLC tiebreak test vector. It
also adds explicit wording for invalid per_commitment_secret (which
nicely matches our code already!).

Tor v2 hidden services have been deprecated for a while:
https://blog.torproject.org/v2-deprecation-timeline .
This prevents user from being able to set them in the configuration
and to connect to them while still letting us be able to parse them
for gossip.
Changelog-Deprecated: lightningd: v2 Tor addresses. Use v3. See https://blog.torproject.org/v2-deprecation-timeline.

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.

Equivalent to gossipd/test/run-find_route.c and gossipd/test/run-find_route-specific.c
except they use gossmap.

There are several reports of desynchronization with LND here; a simple
approach is to only have one feerate change in flight at any time.
Even if this turns out to be our fault, it's been a historic area of
confusion, so this restriction seems reasonable.
Changelog-Fixed: Protocol: Don't create more than one feerate change at a time, as this seems to desync with LND.
Fixes: #4152

The main change which affects us is that 2016 blocks to forget a channel
is a fixed number in the spec; we make this clear by renaming the
(developer-only) max_funding_unconfirmed to dev_max_funding_unconfirmed
and making it compile DEVELOPER only.

They're not defined to be, though we've not seen this on Linux (testing
showed that it is page-level atomic, which means it can still happen across
page boundaries though!). This was pointed out by whitslack in
https://github.com/ElementsProject/lightning/issues/4288
In practice, this just means not complaining when it happens, and also
not trying to get tricky to use it on MacOS (we can safely seek & write,
since we're single-threaded).

Changelog-Removed: Removed bogus UNUSUAL log about gossip_store 'short test'.
You can now activate dual-funded channels using the
`--experimental-dual-fund` flag
Changelog-Changed: Config: `--experimental-dual-fund` runtime flag will enable dual-funded protocol on this node
clang 10.0.0 (erroneously?) claims an enum_side cannot be >= NUM_SIDES.
Make it clear that we're testing the raw u8 for validity.

It's not unheard of for people to give the wrong funding tx to us,
getting their funds stuck. Interestingly, we can allow mutual close
using a different txid and output number as long as they (solely)
funded the channel, and the channel hasn't been used.
This defines a "play area" feature to do just that.

We consolidate to the latest/singular RFC patch for dual-funding, so
there's just a single patchfile for the change. Plus we move back to the
opener setting the desired feerate, the accepter merely declines to
participate if they disagree with the set rate.
