* typecheck client selected by keystore - check if plugin types match
* add log msg + refactor if branching
* moved type check to own function; moved from 'client_for_keystore' to 'force_pair_xpub' and 'client_by_xpub'
* refactor

ledger now gives an error if querying xpub while device is not (unlocked and in bitcoin app).
we do query the xpub however, to calc root fingerprint to be used as soft device id.

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.

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)

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).
previously, client.handler was sometimes
- an InstallWizard
- a QtHandlerBase where win was an ElectrumWindow
- a QtHandlerBase where win was an InstallWizard
- a CmdLineHandler
That's just too much dynamic untyped undocumented polymorphism...
Now it will never be an InstallWizard (replaced with QtHandlerBase where win is an InstallWizard),
and now in all cases client.handler is an instance of HardwareHandlerBase, yay.

old style "-v" still works
filtering examples:
-v=debug,network=error,interface=error // effectively blacklists network and interface
-v=warning,network=debug,interface=debug // effectively whitelists network and interface

^ GUI did not contain any info about failure
we should not raise generic Exception when wanting to communicate with
the user. it makes distinguishing programming errors and messages hard,
as the caller will necessarily need to catch all Exceptions then
