Previously if the user tried to pay an invoice, we tried to construct
a tx with the desired feerate. If this raise NotEnoughFunds, we would just
show the error and not let the user change the feerate.

conceptually did not really make sense that the Exception_Hook kept a reference
to an ~arbitrary main window (preventing gc)
* Add --fingerprint option
* Simplify conditional checks
* Improve warning wording
* Throw error instead of logging and returning
* --fingerprint => --serverfingerprint
* Only run fingerprint checks against main server
* Throw error if --serverfingerprint is set for a non SSL main server
* Fix linting errors
* Don't check certificate fingerprint in a seperate connection
* Disallow CA signed certs when a fingerprint is provided
* Show clear error and then exit for Qt GUI users
* Remove leading newlines from error dialog
* Always check is_main_server() when getting fingerprint
* Document how to generate SSL cert fingerprint
Previously all the interfaces used either "t" or "s".
Now the network only tries to use "s" for all interfaces, except for
the main interface, which the user can manually specify to use "t".
(so e.g. if you run with "--server localhost:50002:t", the main server will use "t",
but all the rest will use "s")
There is a standardised location along with reserved hotkey for "Preferences"
in applications on macOS. Let's put *another* preferences menu item there.
The duplicate items ensure that
- an electrum user coming from a different OS,
- a macOS user used to the standardised preferences location,
will both find "Preferences" easily.
This commit adds support for the BitBox02 hardware wallet.
It supports both single and multisig for the electrum gui wallet.
To use the plugin a local installation of the BitBox02 python library is
required. It can be found on PiPy under the name 'bitbox02' and can be
installed from the bitbox02-firmware repository in the py/bitbox02
directory.
All communication to and from the BitBox02 is noise encrypted, the keys
required for this are stored in the wallet config file under the
bitbox02 key.
The BitBox02 registers a multisig configuration before allowing
transaction signing. This multisig configuration includes the threshold,
cosigner xpubs, keypath, a variable to indicate for mainnet and testnet,
and a name that the user can choose during configuration registration.
The user is asked to register the multisig configuration either during
address verification or during transaction signing.
The check the xpub of the BitBox02 for other hardware wallets, a button
is added in the wallet info dialog.
The wallet encryption key is fetched in a separate api call, requiring a
slightly tweaked override version of the wallet encryption password.

When on dialog n user presses "Back",
- previously, we went back to when dialog n-1 appeared
- now, go back to just after dialog n-2 finishes
This way, any calculations between when dialog n-2 finishes and
dialog n-1 appears will rerun, potentially populating dialog n-1 differently.
Namely if the user presses back on the confirm_seed_dialog, we want to
go back to the show_seed_dialog but with a freshly generated seed.

RuntimeError: wrapped C/C++ object of type PasswordLineEdit has been deleted
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)
