The keystore does not have a "client" field.
One is supposed to use the "get_client" method instead (the generic API is `plugin.get_client(keystore)`)
Remnants of old code.
In multisig, we plan to allow other kinds of keypaths that are not
exactly 4 elements long. This change allows parsing the account
keypath for any kind of keypath, assuming the last two element are /change/address.
The keystore logic would need to be significantly changed to nicely
interoperate with StoredDict/json_db logic.
(just see KeyStore.__init__() and KeyStore.dump())
For now we exempt the keystore from the recursive StoredDict conversion, as
it is a smaller change that is also easier to review for correctness.

Without it, if you have say a 1-of-2 multisig with two BitBox02s, you
would run into trouble if the first keystore would try to match to the
wrong inserted BitBox02 (wrong order, or the first one is not
inserted, etc. ).
With the soft device id, the device manager can figure it on its own
which keystore belongs to which connected bb02.
- for symmetry with other plugins
- and because this is a superset. txin.utxo gets populated from the wallet db (or network);
but the wallet db does not import txs from txin.utxo (so if a psbt already had an
unknown tx there, it will not get imported)
Inform the user that they need to upgrade if their firmware version is
out of date.
The previous `check_device_firmware_version()` was dead code, and the
bb02 function called inside also does not exist.
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.
