Rusty Russell b263c7d2e4 lightningd: documentation updates.
1. announce-addr-discovered-port takes a port option.
2. accept-htlc-tlv-types was deprecated in favor of multiple accept-htlc-tlv-type.
3. Document clnrest.py options.
4. Don't list --version twice in lightningd --help (initial_config_opts calls
   opt_register_version() already).

Dusty Daemon c50e93d9fb splice: Move splice to experimental feature bit
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)

splicing: Remove dependency on experimental_dual_fund

Rusty Russell 0f6687ec7b codex32: use "cl" instead of "ms" as our HRP.
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).

Dusty Daemon 4628e3ace8 channeld: Code to implement splicing
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.

Rusty Russell 58327a594f codex32: rework.
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.

[ Aditya modified the tests to work ]

This integrates them with configvars properly: they almost "just work"

plugin can add something to it.

Rusty Russell b9270c564a lightningd: listconfigs update, using configvars code.
listconfigs is convenient, but it doesn't handle multi-options well: it
outputs an object with duplicate fields in this case (e.g. log-file), nor
is it extensible to show more than raw values.

However, listconfigs doesn't do what other list commands do (use a
sub-object "configs") so we can put the new values under that.

Now we wire in the code which gathers configvars and parses from there;
lightningd keeps the array of configuration variables for future use.

own options (including short ones!) and doesn't want to use this
configvar mechanism, so we have a different API for that now.
