c797b6fb20 libplugin: add method string to jsonrpc callbacks, implement generic helpers.
Without knowing what method was called, we can't have useful general logging
methods, so go through the pain of adding "const char *method" everywhere,
and add:

1. ignore_and_complete - we're done when jsonrpc returned
2. log_broken_and_complete - we're done, but emit BROKEN log.
3. plugin_broken_cb - if this happens, fail the plugin.

c5099b1647 libplugin: clean up API.
When we used to allow cmd to be NULL, we had to hand the plugin
everywhere.  We no longer do.

1. Various jsonrpc_ functions no longer need the plugin arg.
2. send_outreq no longer needs a plugin arg.
3. The init function takes a command, not a plugin.
4. Remove command_deprecated_in_nocmd_ok.

d067066b17 common/gossmap: use u64 for all offsets.
Since we don't compact the gossmap on the fly (FIXME!) we can
easily surpass 4GB in the gossmap, and 32 bit offsets are not
sufficient.

I'm a bit surprised we don't crash immediately, but we've definitely
seen issues.

Changelog-Fixed: gossipd: crash errors with large gossip_store (>4MB) growth on longer-running nodes.

538a0076ca topology: call listpeerchannels_done directly
When cln is run without deprecated apis, the `listchannels` call would
still query `listpeerchannels`, even though it wouldn't use the result.
This adds unnecessary time to the call. Especially in case the node has
many channels. This commit skips the listpeerchannels call in case the
outcome won't be used.

Changelog-Fixed: Improve listchannels performance

5052f0763f gossmap: keep capacity for locally-generated channels as well.
It was weird not to have a capacity associated with localmods channels, and
fixing it has some very nice side effects.

Now the gossmap_chan_get_capacity() call never fails (we prevented reading
of channels from gossmap in the partially-written case already), so we
make it return the capacity.  We do this in msat, because that's what
all the callers want.

Add spendable/receivable and is_local fields to the callback function

e50539d852 pay: ignore fees on our own channels when determining routing.
I noticed that run-route-infloop chose some worse-looking paths after
routing was fixed, eg the second node:

Before:
	Destination node, success, probability, hops, fees, cltv, scid...
	02b3aa1e4ed31be83cca4bd367b2c01e39502cb25e282a9b4520ad376a1ba0a01a,1,0.991856,2,1004,40,2572260x39x0/1,2131897x45x0/0

After:
	Destination node, success, probability, hops, fees, cltv, scid...
	02b3aa1e4ed31be83cca4bd367b2c01e39502cb25e282a9b4520ad376a1ba0a01a,1,0.954540,3,1046,46,2570715x21x0/1,2346882x26x14/1,2131897x45x0/0

This is because although the final costs don't reflect it, routing was taking
into account local channels, and 2572260x39x0/1 has a base fee of 2970.

There's an easy fix: when we the pay plugin creates localmods for our
gossip graph, add all local channels with delay and fees equal to 0.
We do the same thing in our unit test.  This improves things across
the board:

Linear success probability (when found): min-max(mean +/- stddev)
	Before: 0.487040-0.999543(0.952548+/-0.075)
	After:  0.486985-0.999750(0.975978+/-0.053)

Hops:
	Before: 1-5(2.98374+/-0.77)
	After:  1-5(2.09593+/-0.63)

Fees:
	Before: 0-50848(922.457+/-2.7e+03)
	After:  0-50041(861.621+/-2.7e+03)

Delay (blocks):
	Before: 0-196(65.8081+/-60)
	After:  0-190(60.3285+/-60)

6ee59629f9 lightningd: make listincoming use gossmods_from_listpeerchannels().
We temporarily use a second gossmap so we can just switch private info off
for listincoming and not listchannels.

Note that listchannels now uses the local alias (if no scid), so we have
to change that in the routehint caller.

Since we now *always* use a channel alias in hints if one exists, a
test broke, so fix that.
