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

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)

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.

lnpeer: (trivial) log name for chan.state and chan.peer_state 
IntEnum.__format__ just returns an int:

>>> from enum import IntEnum
>>> class Colours(IntEnum):
...   red = 1
...   blue = 2
...
>>> var = Colours.red
>>> f"{var}"
'1'
>>> f"{var!s}"
'Colours.red'
>>> f"{var!r}"
'<Colours.red: 1>'
