Subject: [PATCH 04/13] lazy wallet utxo sync after broadcasting a tx

- lazy wallet utxo sync after broadcasting tx
- granular lock for `refreshutxos`
- avoid pushing to `forcesyncchan` if not empty
- improve policy for used outpoints; wait for first sync on unsigned tx creation
- fix expire condition
- lock address reading
- fix memory leak
- add rpc client for background ops
- follow naming conventions
- another rename
- compare wallet addresses by value
- small fixes
- add comment
