Rusty Russell c3899806ee common: remove unused io_lock.c
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

Rusty Russell 4ffda340d3 check: make sure all files outside contrib/ include "config.h" first.
And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).

config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.

Rusty Russell 0b45d862fe log: don't leak log prefixes.
Do proper refcounting on log prefixes; previously we kept them around,
which is fine, but the extra notleak() and backtrace in developer mode
could get quite heavy (I ended up with 1G of backtraces!).  This is
mainly due to creating one on every JSONRPC command, and running
clboss.

Rusty Russell 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).

niftynei 71a4a2e31c df: rework closing logic
Trying to put all the disconnect logic into the same path was a dumb
idea. If you asked to reconnect but passed in an 'unsaved' channel, we
would not call the 'reconnect' code.

Instead, we make a differentiation between "unsaved" channels
(ones that we haven't received commitment tx for) and handle the
disconnect for these separate from where we want to do a reconnect.
