Make update_local_channel use a timer if it's too soon to make another
update.
1. Implement cupdate_different() which compares two updates.
2. make update_local_channel() take a single arg for timer usage.
3. Set timestamp of non-disable update back 5 minutes, so we can
always generate a disable update if we need to.
4. Make update_local_channel() itself do the "unchanged update" suppression.
gossipd: clean up local channel updates.
5. Keep pointer to the current timer so we override any old updates with
a new one, to avoid a race.

Normally we'd put a pointer into struct half_chan for local
information, but it would be NULL on 99.99% of nodes. Instead, keep a
separate hash table.
This immediately subsumes the previous "map of local-disabled
channels", and will be enhanced further.

Write helpers to split it into non-timestamp, non-signature parts,
and simply compare those. We extract a helper to do channel_update, too.
This is more generic than our previous approach, and simpler.

This avoids having to correlate with listpeers for the most pertinent
information.
This API predates plugins, otherwise we'd have listutxos and listpeers
and this would simply combine them appropriately. Still, it exists so
there's little reason not to make it more friendly.

We used to append new patches to a single file. This caused
some problems and is a lot harder to cleanup later.
This patch moves the experimental patches to their own, individual
patch files, that are named for the current BOLTVERSION, which they're
taken from.
Also moves the current patchfile over to a 'gossipqueries' one,
as it already exists.
The simplest case is to explicitly load it when we see it's been
set.
This involves neatening the default config setup, to remove it from
opt_parse_from_config() and into the caller. It also seems we don't
need to call it anymore before parsing early options: none of them
need ld->config set.
Closes: #3030

For memory-usage reasons, struct chan doesn't use a tal destructor, in
favor of us calling free_chan in the right places.
In DEVELOPER mode, we should check that is the case.

There are some more #if DEVELOPER one-liners coming, this makes them
clear, but still lets them stand out.

We've been slack, but it's going to be important for testing
ratelimiting. And it currently has a minor memory leak.

After switching to a plugin, we verify that we can fund a channel
before we check to contact a peer. We'll need to have a funded wallet
to pass the check in this test that verifies that 'fundchannel' cannot
be called for a peer after fundchannel_start is.
