LnFeatures.supports() is became part of the hot path of
LNPathFinder.find_path_for_payment()
in 6b43eac6fd,
which made find_path_for_payment considerably slower than before.
It used to take around 0.8 sec originally, then after linked commit went to ~9 sec,
and now this takes it down to ~1.1 sec (on my laptop).
otherwise I can't click on list items if the window is moved too far to the right :O

Note: on modern Android, apps don't always run full-screen.
You can pop them out into small windows and move them.
Haven't tested how the deadzones work then though.

- client requests payment_hash from the server
- client sends an invoice with that hash
- client waits to receive HTLCs, then broadcasts funding tx
This means that we now use same script for normal and reverse swaps.
The new flow is enabled by setting option LIGHTNING_SWAP_HTLC_FIRST
in the client. The old protocol is still supported server-side.

- rename trampoline_forwardings -> final_onion_forwardings,
because this dict is used for both trampoline and hold invoices
- remove timeout from hold_invoice_callbacks (redundant with invoice)
- add test_failure boolean parameter to TestPeer._test_simple_payment,
in order to test correct propagation of OnionRoutingFailures.
- maybe_fulfill_htlc: raise an OnionRoutingFailure if we do not have
the preimage for a payment that does not have a hold invoice callback.
Without this, the above unit tests stall when we use test_failure=True
- introduce SentHtlcInfo named tuple
- some previously unnamed tuples are now much shorter:
create_routes_for_payment no longer returns an 8-tuple!
- sent_htlcs_q (renamed from sent_htlcs), is now keyed on payment_hash+payment_secret
(needed for proper trampoline forwarding)
- add RecvMPPResolution enum for possible states of a pending incoming MPP,
and use it in check_mpp_status
- new state: "FAILED", to allow nicely failing back the whole MPP set
- key more things with payment_hash+payment_secret, for consistency
(just payment_hash is insufficient for trampoline forwarding)
The "python:rc" tag on dockerhub has not been updated for 2+ years
and is still at 3.10.0rc2. Even 3.11 has been released for many months now.

Without this,
`$ python3 -m unittest electrum.tests.regtest.TestUnixSockets.test_unixsockets`
was failing on my machine but succeeding on CI, due to timing differences.
