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.

scenario1:
- 2of2 multisig wallet with trezor1 and trezor2 keystores
- only trezor2 connected
- previously we would pair first keystore with connected device and then display error.
now we will pair the device with the correct keystore on the first try
scenario2:
- standard wallet with trezor1 keystore
- trezor2 connected (different device)
- previously we would pair trezor2 with the keystore and then display error.
now we will prompt the user to select which device to pair with (out of one)

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.
