3a35f90aa0 Do not use network callback to update channel states; call LNWorker methods directly instead. 
A callback was used because a single LNWnwatcher object used to be shared for all wallets.
Since wallet now have their own LNWatcher instance, this can be simplified.

36f32651cc Define network.try_broadcasting() method. 
Use it when rebroadcasting a force-close tx,
because the channel state is already set.

split network main_taskgroup: create daemon.taskgroup 
network.main_taskgroup restarts every time the proxy settings are changed,
many long-running tasks (some introduced with lightning) are not prepared for and do not want this.
