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).
