payto_e.lightning_invoice has to be set after the payment field is set
to the node pub key, because check_text has the side effect of resetting
the payto_e.lightning_invoice
When changing e.g. from mBTC to BTC, the history list was only
partially updated: the displayed amounts got updated but the
displayed unit did not, so incorrect information was shown.
Previously if there was a chain of exceptions, we were only
sending the traceback for the final exception.
E.g.
try:
raise ExcOne("asdasd")
except ExcOne() as e:
raise ExcTwo("qweqwe") from e
^ we would lose all info about ExcOne, including potentially many lines of trace

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:
https://github.com/Electron-Cash/Electron-Cash/pull/1376

- fix kivy wizard restore-from-seed
- qt seed dialog: disable "next share" if current share is invalid
- fix tests: file paths should not depend on $PWD (working dir)
Previously if the wallet did not have a deterministic node id,
the wallet info dialog could say "lightning enabled, non-recoverable channels", but
the "recoverable channels" setting could be toggled and might even say "yes".
