75720ad0e1 lightningd: wait for gossipd to finish initalizing before starting plugins.
This mainly helps our CI under valgrind, which starts a fresh instance
and immediately calls the invoice command.  This can cause the topology
plugin to try to access the gossmap file before it's created.

We can also move the gossmap reading in topology to init time.

7e7ab4cb3b gossipd: remove routing, listchannels and listnodes infrastructure.
This involves removing some fields from the now-misnamed routing.h
datastructures, and various internal messages.

One non-obvious change is to our "keepalive" logic which refreshes
channels every 13 days: instead of using the 'enabled' flag on the
last channel broadcast to decide whether to refresh it, we use the
local connected status directly.

cda8f8190b invoice: overhaul routehints to use topology.listincoming, cleanup.
This turned into a more extensive cleanup than intended.  The previous
warnings were overlapping and confusing, especially now MPP is the norm.

*warning_capacity* is now the "even under best circumstances, we don't
have enough incoming capacity", which is really what
warning_mpp_capacity was trying to say (no longer printed).

*warning_offline* and *warning_deadends* are only given if adding such
peers would have helped give capacity (i.e. not if *warning_capacity*
is set).  The new *warning_private_unused* tells you that we would
have sufficient capacity, but we refused to expose private channels.

The test cases have been enhanced to cover the new warnings.

Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Added: JSON-RPC: `invoice` now gives `warning_private_unused` if unused unannounced channels could have provided sufficient capacity.
Changelog-Changed: JSON-RPC: `invoice` warnings are now better defined, and `warning_mpp_capacity` is no longer included (since `warning_capacity` covers that).

9e1b830191 plugins/topology: listincoming function to help invoices.
Invoices need to know what the peers' update contains, to create
routehints.  It also wants to know if a peer has no other public
channels (so-called "dead end" peers) to eliminate them from routehint
consideration.

This was previously done by a special function to ask gossipd.

Only v0 has specific length restrictions: taproot is v1 32 bytes long,
but explicitly other lengths remain undefined.

I noticed that I added option_shutdown_anysegwit as EXPERIMENTAL in

non-experimental as a spec update, but didn't CHANGELOG it then
either, so let's do that now!
