RunCoroutineDialog has a run() method that blocks the thread
without blocking the GUI (using exec), and a Cancel button
that cancels the coroutine.
main_window.run_coroutine_dialog() is a wrapper that returns
the coroutine result and may raise exceptions.
BlockingWaitingDialog was removed is transaction_dialog,
where it was not particularly useful.
I just had a channel force-closed over a fee-estimate-disagreement :(
Scenario:
1. started electrum, opened wallet
2. waited around 10 seconds, opened the lightning channels overview, saw that channels are open/ready
3. after around 10 more seconds, scanned bolt11 invoice and tried to pay
4. channel got force-closed
Before this commit, we only call maybe_update_fee via lnwatcher callbacks.
These callbacks trigger on events such as "adb_set_up_to_date", "blockchain_updated", "network_updated", "fee".
In my case there was a race that all these events triggered *before* the channel got reestablished
(in fact before the peer handshake finished). And also, by chance there were none of these events after
the reestablish but before I sent the HTLC.
When I sent the HTLC, the channel counterparty (eclair) sent back an "error" msg that the feerates are
too different, which led us to do a local-force-close.
I have other channels in this wallet (with other peers), which reestablished faster and got lucky with
timing: the lnwatcher callbacks came just in time to trigger update_fee for them.

yay
Given how few providers have free historical APIs, each one is very much appreciated.
They are doing a public service. Thanks. Not that they ever read commit messages. :)

- include a copy of pinmatrix.py from python-trezor, as-is
- adapt that to qt6: the upstream version(s) only support qt4/qt5
- use it in trezor/keepkey/safet plugins
