In the past, when creating payment requests, we keyed them by on-chain address,
and set/saved the msg of the request as label for the address.
Many places in the code were calling wallet.get_label(addr) with the expectation that
relevant payment requests are found and their message/description (if any) is considered.
wallet.get_label(key) is now made private, and instead the explicit non-polymorphic
wallet.get_label_for_{address,rhash,txid} alternatives should be used.

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)
- 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
- separate AddressSynchronizer from Wallet and LNWatcher
- the AddressSynchronizer class is referred to as 'adb' (address database)
- Use callbacks to replace overloaded methods
- use SetMinimumSize instead of sizeHint
(partially reverts 28f794b63b)
- to deal with small window sizes, set MinimumHeight of the
parent TabWidget (with a few extra pixels for margins)
- add an extra layout around address_help_text, so that it has
margins (margins were removed in 28f794b63b)
Previously the receive_tabs widget was allowed to be much smaller
than its inner main widget (e.g. truncating visible QR code).
A bit hackish to overwrite/monkeypatch sizeHint,
but I've tried a few approaches and this seems to work best.
Disable rebalance/swap suggestions attached to requests/invoices if there is an ongoing task.
Note: This assumes that all tasks are lightning payments, which is true for the moment.
These methods return a list of channels that can be rebalanced,
in order to receive or send a given amount.
Also add 'channels' parameter to submarine swaps.
Previously, swaps were not considering which channel to use.
When we do not have liquidity to pay an invoice:
- add 'rebalance' option in order to pay an invoice
- use the suggested channel in the 'swap' option
When we do not have the liquidity to receive an invoice:
- add 'Rebalance' and 'Swap' buttons to the receive tab
I believe lightning requests created before https://github.com/spesmilo/electrum/pull/7730
can have an amount of None - ones created after have amount 0 instead.
We could do a wallet db upgrade potentially.
Regardless, the type hint is `get_amount_sat(self) -> Union[int, str, None]`,
so None should be handled. (well, arguably "!" should be handled too...)
