If an attacker has access to the process' memory, it's probably already game over,
still we can make their life a bit harder.
I really tried but failed to encapsulate this logic inside PasswordLineEdit.
The destroyed signal arrives too late.
deleteLater is not called.
__del__ gets called too late.
Electrum needs either "cryptography" or "pycrytodomex" (since #6014).
Previously we have been using a custom fork (of ours) of pycryptodomex,
now let's just use upstream "cryptography".
- updated p4a pulls in newer openssl (old one is no longer available from openssl.org)
- old NDK no longer available (new one is what updated p4a recommends)
transitions, and actions taken as a result.
- state transitions are performed in lnchannel.update_onchain_state()
- peer actions are in LNWorker.on_channel_update()
Just makes sense in general.
Also, previously, the GUI would freeze if right after startup the user
clicked the hww status bar icon (especially with multiple hww connected).

When initialising a Trezor as part of the wallet creation,
device_info.label is still the old (None) label in on_hw_derivation.
This is because device_info was created during the initial scan.
