After some consideration I am fairly certain there is no need to take
wallet.lock in `is_up_to_date()`. Any caller that might want some kind
of guarantees re the value returned by is_up_to_date() would need to
enforce them itself by e.g. taking wallet.lock around its critical code
block. That is, even if is_up_to_date() itself takes the lock, between
the call returning and the caller reading the value there could still
have been a race.
Also, the GUI was directly accessing the field already.
wallet.thread was serialising the fut.result() calls, so consider e.g.
- coro1 gets scheduled,
- wallet.thread waits on fut1.result()
- coro2 gets scheduled,
- coro2 finished with exception and wants to show an error popup,
-> wallet.thread is still waiting on fut1.result() before it looks at fut2.result
fixes https://github.com/spesmilo/electrum/issues/7750
Each task we schedule on `TaskThread` can provide an optional `cancel` method.
When stopping `TaskThread`, we call this `cancel` method on all tasks in the queue.
If the currently running task does not implement `cancel`, `TaskThread.stop` will block
until that task finishes.
Note that there is a significant change in behaviour here:
`ElectrumWindow.run_coroutine_from_thread` and `ElectrumWindow.pay_lightning_invoice`
previously serialised the execution of their coroutines via wallet.thread.
This is no longer the case: they will now schedule coroutines immediately.
So for example, the GUI now allows trying to pay multiple LN invoices "concurrently".
Use refresh_row() for address, utxo and contact lists.
Replace unneeded calls to update_tabs() with refresh_tabs()
Fix right-click menu after selecting multiple addresses.
