ThomasV had libffi installed via brew, and this side-effected the built electrum dmg.
`('libffi.8.dylib', '/usr/local/opt/libffi/lib/libffi.8.dylib', 'BINARY')`
this was the cause of 019d213325
Which means we need *both* xcode cli tools and full xcode.
Document this weirdness, including the exact paths they should be at.

Error: Xcode alone is not sufficient on Mojave.
Install the Command Line Tools for Xcode 11.3.1 from:

```
- added notes about reproducibility requirements
- adapted build scripts from Bitcoin Core that can
- extract signatures from a signed .app
- apply previously extracted signatures to an unsigned .app
Turns out the Xcode CLI tools are still not enough, and we need full Xcode :(
This is only for notarization; as `altool` (which we need there) is only part
of full Xcode. So we need to download 8 gigs just for that single script...

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:
