In particular, window.timer_actions() calls
request_list.refresh_all() and invoice_list.refresh_all(),
every 0.5 seconds.
We avoid doing this at least when those lists are not visible anyway.
- set minimumHeight of VTabWidget (needed for small window size)
- keep self.tabBar visible, otherwise the widget border is rendered with a gap on linux
- apply stylesheet to both tabTar and surrounding widget
- buttons style: align text left, NoFocus
- on button click: setChecked always True, draw qr code at the end because it is slow
QTabWidget with "West" tab pos and horizontal text looks completely broken on macOS
(despite looking good on e.g. Ubuntu GNOME and Windows).
The alternative here looks ok on all three OSes.

Re FIXME in main_window.py, in particular, adb might call `add_transaction` on the same tx multiple times.
In `wallet.on_event_adb_added_tx`, maybe we should propagate `notify_GUI` to `wallet._update_request_statuses_touched_by_tx`.
The issue being fixed here (above TARS reports) can be triggered in multiple ways, e.g.:
- have an already paid receive request, and receive a payment to the same address again
- have an already paid receive request, and *spend from* that address (in which case the history of the address will change, and address_synchronizer will call add_transaction again on the old tx that satisfied the old receive request)

Buttons Editor: Make background non-transparent and change to push button
There were some issues with transparent backgrounds with QToolButton on
Linux and as there is no real reason for them to be transparent we just
make them opaque.

Pay to editor: Fix size computations to use the proper values
Previously this did not take into account the spacing between lines nor
the margins of the control and the document. There is also a sensible
minimum height of one line now and it expands to up to 10 lines before
we show the scroll bar. When the scroll bar is active, we move the buttons
so they do not obscure the scroll bar.

Buttons Editor: Add transparent border which is somehow needed for correct macOS layout
- show payment options in tabs: URI, Address or Lightning
- use vertical tabs to save space
- switch between QR and text views
- open standalone QR window through menu, instead of clicking on QR code

Each task we schedule on `TaskThread` can provide an optional `cancel` method.
When stopping `TaskThread`, we call this `cancel` method on all tasks in the queue.
If the currently running task does not implement `cancel`, `TaskThread.stop` will block
until that task finishes.
Note that there is a significant change in behaviour here:
`ElectrumWindow.run_coroutine_from_thread` and `ElectrumWindow.pay_lightning_invoice`
previously serialised the execution of their coroutines via wallet.thread.
This is no longer the case: they will now schedule coroutines immediately.
So for example, the GUI now allows trying to pay multiple LN invoices "concurrently".
This commit ports the work of EchterAgo and cculianu from Electron-Cash,
to implement a new toolchain to scan qr codes.
Previously, on Linux and Win, we have been using zbar to access the camera
and read qrcodes; and on macOS we used CalinsQRReader (an objective-C
project by cculianu).
The new toolchain added here can use QtMultimedia to access the camera,
and then feed that image into zbar. When used this way, zbar needs
fewer dependencies and is easier to compile, in particular it can be
compiled for macOS.
The new toolchain works on all three platforms, with some caveats
(see code comments in related commits) -- so we also keep the end-to-end
zbar toolchain; but at least we can drop CalinsQRReader.
The related changes in Electron-Cash are spread over 50+ commits (several PRs and direct
pushes to master), but see in particular:

This fixes the case where the user quits by pressing Ctrl+C,
and some other minor things.
There is still another issue that sometimes causes a segfault during shutdown...
Sometimes we want its "remember path" behaviour but it does not make sense to
parent the dialog from main window. When so, caller code no longer needs to
get a reference to a main window.
Also rm last usages of get_parent_main_window().
On Linux, when Electrum is executed from Appimage file, to prevent system library
inconsistence for Electrum and web browser and all issues involving that,
Electrum starts web browser and opens web page upon clicking on
'View on block explorer' by fork()'ing the process, unsetting
its custom LD_LIBRARY_PATH environment variable in the child process,
and calling webbrowser.open().
Due to incorrect usage of sys.exit() instead of os._exit() for child process,
Electrum (parent) can't be terminated and endlessly waits for child process upon
exit, while child process does nothing but still exists.
Fix this issue by using os._exit function, which should be used for
child processes (not only in Python).
