This is most useful when receiving MPP where there is a non-trivial chance
that we have received some HTLCs for a payment but not all, and the user
closes the program. We try to fail them and wait for the fails to get
ACKed, with a timeout of course.
A penalty is added for split configurations which saturate a channel.
Saturation of channels is discouraged as we don't know the fees
beforehand. The penalty is accomplished via an exponential function that
kicks in when the subamount reaches about the total funds available
(this amount is controlled by the parameter EXHAUST_DECAY_FRACTION).

Pre kivy 2.0, "orientation" was undefined for GridLayouts, not sure why we were setting it, it was a no-op.
kivy 2.0 added meaning to the field, and the values we were setting it to are invalid.

The test failures corresponding to single-part (non-MPP) payments expose a bug.
see 196b4c00a3/electrum/lnpeer.py (L1538-L1539)
`lnworker.add_received_htlc` is not called for single-part payments...
