qml: add signals for QEQRScanner and fallbacks, add QEBytes container type
so we can pass along byte arrays between QML and python, port qr scan
occurrences to new signals.
Previously the server parameters were each handled differently, e.g. auto-connect was only applied when updating Network.server
and not when Config.autoConnect was updated. Similarly, updating Network.server did not restart the network, leading to >1 connection
when Network.oneServer was set to True before updating Network.server.
Consolidate server parameter updates into a single call, remove the individual setters, and move Config.autoConnect and Config.autoConnectDefined to Network.
- Wallet.make_unsigned_transaction takes a FeePolicy parameter
- fee sliders act on a FeePolicy instead of config
- different fee policies may be used for different purposes
- do not detect dust outputs in lnsweep, delegate that to lnwatcher
allow enable/disable proxy without nuking proxy mode, host and port (explicit enable_proxy config setting),
move tor probe from frontend to backend code, add probe buttons for Qt and QML
In some cases this makes it much easier to successfully scan a QR code.
I was trying to scan a PSBT using a laptop camera from my phone screen for 2 minutes, until I realised the screen brightness was the issue. o.O

This is a bit ugly, but activeFocus is declared as final and cannot be overridden directly...

```
turns out that Qt.inputMethod.keyboardRectangle.height is not suitable for calculating the exact keyboard
dimensions in Qt coordinates. Instead, use Qt.inputMethod.keyboardRectangle.y transformed to Qt coordinates
using Screen.devicePixelRatio
Note: Qt.inputMethod.keyboardRectangle stop being updated after exiting FLAG_SECURE state
(e.g. in seed or master key entry pages)
The following exceptions should be expected:
FileNotFoundError: given wallet path does not exist
StorageReadWriteError: given file is not readable/writable or containing folder is not writable
InvalidPassword: wallet requires a password but no password or an invalid password was given
WalletFileException: any internal wallet data issue. specific subclasses can be caught separately:
- WalletRequiresSplit: wallet needs splitting (split_data passed in Exception)
- WalletRequiresUpgrade: wallet needs upgrade, and no upgrade=True was passed to load_wallet
- WalletUnfinished: wallet file contains an action and needs additional information to finalize. (WalletDB passed in exception)
Removed qml/qewalletdb.py
This patch also fixes load_wallet calls in electrum/scripts and adds a qml workaround for dialogs opening and closing so
fast that the dialog opened==true property change is missed (which we need to manage the dialog/page stack)
