If you previously configured with `--enable-developer` we turn that into `--enable-debugbuild`.

Changelog-Removed: build: `--enable-developer` arg to configure (and DEVELOPER variables): use `./configure --enable-debugbuild` and `developer` setting at runtime.
Also requires us to expose memleak when !DEVELOPER, however we only
ever used the memleak tracking when the LIGHTNINGD_DEV_MEMLEAK
environment variable was set, so keep that.

Currently it just defaults to the DEVELOPER compile option, but we'll
move over to this.

Changelog-Added: Config: `--developer` enables developer options and changes default to be "disable deprecated APIs".
Added a test for splicing out that exposed some behavior and code glitches that are addressed in this commit.
Added test for splice gossip.
Also added documentation for how to do a splice out.
ChangeLog-Fixed: Added docs, testing, and some fixes related to splicing out, insufficent balance handling, and restarting during a splice.
json_add_timeabs only printed in milliseconds and json_add_time outputs a string which is weird
Changelog-Changed: JSON-RPC time fields now have full nanosecond precision (i.e. 9 decimals not 3): `listfowards` `received_time` `resolved_time` `listpays`/`listsendpays` `created_at`.
Since we changed the default, it used to be required to set it. That was a while ago, though, so we can make it optional again.
Changelog-Changed: Protocol: `invoice` no longer explicitly encodes `c` if it's the default (18)

We were allowed to, but the spec removed that. So we handle warnings
differently from errors now.
This also means the LND "internal error" workaround is done in
lightningd (we still disconnect, but we don't want to close channel).

Changelog-Changed: Protocol: we no longer disconnect every time we receive a warning message.
Doesn't happen on x86, but struct gossmap_chan defines:
```
u32 private: 1;
u32 plus_scid_off: 31;
```
And complains when we initialize plus_scid_off and access it later:

As side-effect, getroute(0) is special too.

Fixes: #6577
Changelog-Fixed: `pay` will still use an invoice routehint if path to it doesn't take 1-msat payments.
This should provide the default help message and exit, but was
resulting in a segmentation fault from freeing pointers passed to
the default config.
Changelog-Fixed: lightning-cli properly returns help without argument
This is actually a valid complaint (though this is a sanity check for
things we make ourselves, still!).

This was recommended by @t-bast: if the final spec commits to something
compatible, we can simply advertize and accept both features, but if it
does change in incompatible ways we won't cause problems for nodes
who implement the official spec.
(I split this, so first, we remove the OPT_SPLICE entirely, to make
sure we caught them all. --RR)

I obviously like the word "capabilities" since I reused it to refer
to the HSM's overall features :(

This was strongly recommended by Russell O'Connor: the "ms" implies that
it's a BIP-32 master secret, and this is CLN specific.
If we changed the hrp to "cln" it would be better, but apparently that
means we no longer fit in a "standard billfold metal wallet" (and
our code assumes a 2-byte prefix anyway).

Update the lightningd <-> channeld interface with lots of new commands to needed to facilitate spicing.
Implement the channeld splicing protocol leveraging the interactivetx protocol.
Implement lightningd’s channel_control to support channeld in its splicing efforts.
Changelog-Added: Added the features to enable splicing & resizing of active channels.
New daemon process means we don’t have to deal with gossip, so that gets removed along with error cleanup and a refactoring of how we calculating PDBT diffs.
Update gossip routiens and various other hecks on the channel state to consider AWAITING_SPLICE to be routable and treated similar to CHANNELD_NORMAL.
Small updates to psbt interface

Firstly, I wanted the results easier to use:
1. Make them always lower case, even if the string was UPPER.
2. Decode the payload for them.
3. Don't give the user any fields they don't need, and make
the field sizes explicit.
Secondly, I wanted to avoid the pattern of "check in one place, assume
in another", in favour of "check on use".
So, I changed the code to lower the string if it needs to at the start,
and then changed the pull functions so we always use them to get data:
this way we should fail clearly and gracefully if we don't have enough data.
I made all the checks explicit, where we assign the fields.
I also addressed the FIXME: I think the array is *often* one shorter,
but not always, so I trim the last byte at the end if needed.

Nothing major here:
1. size_t for lengths.
2. pass engine to checksum_verify, as caller wants ->len (avoid repeating 13/15 magic numbers).
3. Use x.member instesad of (&x)->member.
4. Return memcmp result directly instead of if.
5. Spacing removal, `;;` removal.
6. codexl is a bool `true`/`false` not 0/1 (it's the same, but clearer)
7. Make sanity_check assign *fail directly.

Clean restart of daemon after a tx-abort is a nice way to work around
the 'persistent' disconnect that we t-bast noticed.
Changelog-Fixed: `dualopend`: Fix behavior for tx-aborts. No longer hangs, appropriately continues re-init of RBF requests without reconnction msg exchange.
