06dfe1699c LNWatcher: Distinguish between blockchain-triggered channel state 
transitions, and actions taken as a result.

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.

- request the highest ctn from sweepstore using get_ctn
- send sweeptxs asynchronously in LNWallet.sync_with_watchtower
