aacddf008c trigger_force_close: set my_current_per_commitment_point to a valid point 
We could as well derive the point from our channel_seed and ctn=0,
but that seems unnecessary. Related: #6241

5401b3f72d channel backups: try fixing force-close-trigger 2020-06-19 06:38:00 +02:00

4c70956687 filter callbacks to wallet: channel, payment_succeeded, payment_failed 
It is ugly that the 'channel' callback takes a wallet I guess,
but with channel backups in one wallet, and active channels in another,
it was causing problems... (when open simultaneously)

530a446172 follow-up prev: don't reuse funding tx change address for static_remotekey

6040e953a3 wallet: implement reserving addresses, and use it for LN SRK to_remote 
- Use change addresses (instead of receive) for the static_remotekey to_remote outputs,
  and reserve these to greatly reduce the chance of address-reuse
- Use change addresses (instead of receive) for LN channel sweep addresses.
  Note that these atm are not getting reserved.

'1'
