```
In SendTab.broadcast_transaction.broadcast_thread, self.payto_e.payment_identifier was referenced -
but do_clear() has already cleared it by then.
E.g. consider SendTab.pay_onchain_dialog: it calls save_pending_invoice(), which calls do_clear(),
and later (in sign_done), it calls window.broadcast_or_show, which will call SendTab.broadcast_transaction().
As there might be multiple independent transaction dialogs open simultaneously, the single shared state
send_tab.payto_e.payment_identifier approach was problematic -- I think it is conceptually nicer to
pass around the payment_identifiers as needed, as done with this change.
However, this change is not a full proper fix, as it still somewhat relies on
send_tab.payto_e.payment_identifier (e.g. in pay_onchain_dialog). Hence, e.g. when using
the invoice_list context menu "Pay..." item, as payto_e.payment_identifier is not set,
payment_identifier will be None in broadcast_transaction.
but at least we handle PI being None gracefully -- before this change, broadcast_transaction
expected PI to be set, and it was never set to the correct thing (as do_clear() already ran by then):
depending on timing it was either None or a new empty PI. In the former case, producing the above
traceback and hard failing (not only for bip70 stuff!), and in the latter, silently ignoring the logic bug.
- show a QLineEdit by default, a QTextEdit only if paytomany is active.
paytomany is a rare use case, it should not interfer with regular
use (e.g. when a user inadvertently types enter).
- this also fixes the visual appearance if the payto line
- keep paytomany menu in sync with actual state
- in lnurl.py, make request methods async
- in Qt GUI, lnurl network requests no longer block the GUI thread
- but they still do in the kivy GUI
- "lightning address" (LUD-16) support is removed for now as the
email addresses are indistinguishable from openalias email addresses
(both protocols should have added and enforced a prefix, or similar,
to remove this kind of ambiguity -- now we would need to make a
network request just to identify what kind of ID we were given)
- add param to _check_text to toggle if network requests are allowed ("full check")
- every 0.5 sec, if the textedit has no focus, do full check
- on textChanged()
- detect if user copy-pasted by comparing current text against clipboard contents,
if so, do full check
- otherwise, do partial check
- on clicking ButtonsWidget btns (scan qr, paste, read file), do full check

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.

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:

self.setMinimumHeight(h)
- We need only two types: PR_TYPE_ONCHAIN and PR_TYPE_LN
- BIP70 is no longer a type, but an optional field in the dict
- Invoices in the wallet are indexed by a hash of their serialized list of outputs.
- Requests are still indexed by address, because we never generate Paytomany requests.
- Add 'clear_invoices' command to CLI
- Add 'save invoice' button to Qt
