We still want to test non-anchor channels, as we still support them, but
we've made it non-experimental. To test non-anchor channels, we
use dev-force-features: -23.

Header from folded patch 'fixup!_options__make_anchors_enabled_by_default,_ignore_experimental-anchors.patch':
fixup! options: make anchors enabled by default, ignore experimental-anchors.
The `amount` field is intended to be either a native unit (`msat`,
`sat` or `btc`) or it can also be a non-native unit that needs to be
converted into native when creating the invoice. As such limiting the
`amount` to only be native is very restrictive.
Christian points out that this makes the type harder, and it's just awkward.

Unfortunately, this is awkward: we just copy through most requests,
so we can't easily add a "deprecation" field to each one. So we do
a notification if the next command has a different deprecation status
than the global one, but that requires opt-in from the plugin.
We didn't previously document the subscriptions array, so do that now.

Changelog-Added: Plugins: `deprecated_oneshot` notifiction subscription to change deprecated status for a single command.
I did some CHANGELOG and git digging to see when these were deprecated, and

chose to do so this release only.
I renamed ld's `deprecated_apis` to `deprecated_ok` to make sure I
caught them all.

Changelog-Added: JSON-RPC: `deprecations` to enable/disable deprecated APIs from this caller.
This allows the user to specify the feature *by name*, and hopefully
complain to the developer to fix their code, knowing it will be removed entirely
in the next release!
Changelog-Added: config: `i-promise-to-fix-broken-api-user` allows for a one-release re-enablement of long-deprecated features.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Each feature has a name, and says when deprecation begins and ends.
There's an API coming to allow you to re-enable on a per-feature basis
even if it's ended (as long as it's not been removed from the code ofc!).
Default end is 6 months after deprecation, i.e. we complain about it
at that point, if we can detect its use.
e.g, a standard deprecation in v24.05:
v24.02: allowed
v24.02 with mods: allowed
master after v24.02: allowed unless deprecated APIs disabled.
v24.05: allowed unless deprecated APIs disabled.
v24.08: allowed unless deprecated APIs disabled.
v24.11: allowed unless deprecated APIs disabled, but logs at BROKEN level.
v25.02: allowed only if --i-promise-to-fix-broken-api-user=FEATURE.
v25.05: code is actually removed.

This is good info to have, that I often forget and have to spend time
looking for. It'd be nice to have it documented in the project somewhere
so people new the project (or new to maintaining maybe?) know where to
find it.
In the original [$6173] pr `bind` was a typo for `bind-addr`.
`bind` never existed, so this commit updates uses of `bind` to `bind-addr`.
This links lightningd-config.5.md to configuration.md since `bind-addr` has options of interest such as ipv4/ipv6.
When the value of a `dynamic` option is updated core Lightning
will make a JSON-RPC request to the plugin.
The documentation falsely mentioned the request has a method named
`setvalue. It appears it is actually called `setconfig`.

Changelog-Deprecated: JSON-RPC: `listchannels` listing private channels: use listpeerchannels
This is redundant if it's a public channel, but vital if it's not. Publishing unconditionally makes
it easier for gossmap: we create a local modification all the time, even if redundant (and we can
have the actual capacity ceiling accurate in this case, since we know it for local channels).

Changelog-Added: JSON-RPC: `listpeerchannels` now shows gossip update contents (even if channel unannounced).
The data-format changed in 2019.
The field `amount_msat` was renamed to `msat`
(See 2907e430d5)
The data-format changed again in november 2023.
The content of the field `amount_msat` was changed.
It was a string `"1000msat"` and became a number `1000`.
(See 0b23133ab2)
The current documentation still mentions the data-format before
2907e430d5.
I've updated the docs to reflect the latest changes.
I've also incluced a short mention of 0b23133ab2 to help help
developers create plugins that work both pre 23.11 and post 23.11.

From the spec:
Once peers are ready to exchange commitment signatures, they must remember
the details of the funding transaction to allow resuming the signatures
exchange if a disconnection happens.
Basically this means we add channels to the database before we've gotten
commitments for them; it's nice that there's now a state for commitments
recevied but we now save the channel prior to that.
This commit makes it possible to track the pre-commit-rcvd but not quite
open-init state.

As side-effect, getroute(0) is special too.
Reported-by: MiddleW4y in Discord
Fixes: #6577
Changelog-Fixed: `pay` will still use an invoice routehint if path to it doesn't take 1-msat payments.
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).

Previously, the "payment" and "invoice" paths were completely separate, but this now calls both. It bypasses htlc_sets (and thus, cannot do MPP), and bypasses the hook too: the former is tied closely to HTLCs, and the hook is also very htlc-centric.
