on the upstream channel, before even doing a `commitment_signed`
dance on the downstream channel. This implies that our
`ChannelMonitorUpdate`s "go out" in the right order - first we
ensure we'll get our money by writing the preimage down, then we
write the update that resolves giving money on the downstream node.

order in which they are generated, but of course looking forward we
want to support asynchronous updates, which may complete in any
order.

Here we add infrastructure to handle downstream
`ChannelMonitorUpdate`s which are blocked on an upstream
preimage-containing one. We don't yet actually do the blocking which
will come in a future commit.

Never block a thread on the `PeerManager` event handling lock

will return immediately to avoid blocking more than one thread).

This works fine as long as the user has a spare thread to leave
blocked, but if they don't (e.g. are running with a single-threaded
tokio runtime) this can lead to a full deadlock.

Instead, here, we never block waiting on another event processing
thread, returning immediately after signaling that the first thread
should start over once its complete to ensure all events are
handled.

While this could lead to starvation as we cause one thread to go
around and around and around again, the risk of that should be
relatively low as event handling should be pretty quick, and it's
certainly better than deadlocking.

its range. Further, we only score the immediate path we are
expecting to to send over, and not randomly but rather based on the
amount sent.

Here we try to make the benchmarks a bit more realistic by adding
a new benchmark which attempts to send around 100K sats, which is
a reasonable amount to send over a channel today. We also convert
the scoring data to be randomized based on the seed as well as
attempt to (possibly) find a new route for a much larger value and
score based on that. This potentially allows us to score multiple
potential paths between the source and destination as the large
route-find may return an MPP result.

Fix test_restored_packages_retry serialized monitor payload

The purpose of this payload is to ensure we retry restored packages on a
`ChannelMonitor` that has upgraded from a version that previously did
not have such retry logic. We can verify this works by checking whether
a restored package has a `height_timer` of `None` upon deserializing the
monitor payload.

In the previous commit, we added a helper that constructs blocks
whenever tests demand blocks be connected. This helper moved towards
having all connected blocks have a version of 0x2000_0000 (also known as
NO_SOFT_FORK_SIGNALLING). However, previously, it was possible for some
blocks to be connected with a slighty different version: 0x0200_0000,
resulting in different block hashes.

This block hash divergence prompted a failure in this test when
`ConnectStyle::HighlyRedundantTransactionsFirstSkippingBlocks` is used
for `nodes[0]`, since this block connection style reconfirms
transactions redundantly and the serialized monitor payload kept a
reference to the hash of the block with version 0x0200_0000, when it
should be expecting one with version 0x2000_0000.
