(Re-)add handling for `ChannelUpdate::message_flags`

When the `htlc_maximum_msat` field was made mandatory in
`ChannelUpdate` (in b0e8b739b73cc25f3e1ab00695a14d972162a140) we
started ignoring the `message_flags` field entirely and always
writing `1`. The comment updates indicated that the `message_flags`
field was deprecated, but this is not true - only the
`htlc_maximum_msat` indicator bit was deprecated, requiring it to
be 1.

If a node creates a `channel_update` with `message_flags` bits set
other than the low bit, this will cause us to spuriously reject
the message with an invalid signature error as we will check the
message against the wrong hash.

With today's current spec this is totally fine - the only other bit
defined for `message_flags` is the `dont_forward` bit, which when
set indicates we shouldn't accept the message into our gossip store
anyway (though this may lead to spurious `warning` messages being
sent to peers). However, in the future this may mean we start
rejecting valid `channel_update`s if new bits are defiend.

G8XSU [Fri, 14 Jun 2024 23:56:36 +0000 (16:56 -0700)]
Optimize ChannelMonitor persistence on block connections.

Currently, every block connection triggers the persistence of all
ChannelMonitors with an updated best_block. This approach poses
challenges for large node operators managing thousands of channels.
Furthermore, it leads to a thundering herd problem
(https://en.wikipedia.org/wiki/Thundering_herd_problem), overwhelming
the storage with simultaneous requests.

To address this issue, we now persist ChannelMonitors at a
regular cadence, spreading their persistence across blocks to
mitigate spikes in write operations.

Outcome: After doing this, Ldk's IO footprint should be reduced
by ~50 times. The processing time required to sync each block
will be significantly reduced, particularly for nodes with 1000s
of channels, as write latency plays a significant role in this process.
As a result, the Node/ChainMonitor will be blocked for a shorter
duration, leading to further efficiency gains.

Drop unnecessary key derivation in route tests

In our route tests we need some "random" bytes for the router to
randomize amounts using. We generate this by building an actual
`KeysManager` and then deriving some random bytes using the
`EntropySource` trait. However, `get_route` (what we're normally
testing) doesn't actually use the random bytes, and even if it did,
using a `KeysManager` is just a fancy way of creating a constant,
so there's really no reason to do all the fancy crypto.

Instead, here, we change our routing tests and benchmarks to simply
use `[42; 32]` as the "random" bytes.

Unblock channels awaiting monitor update based on `ChanMan` queue

When we have `ChannelMonitorUpdate`s which are completing both
synchronously and asynchronously, we need to consider a channel as
unblocked based on the `ChannelManager` monitor update queue,
rather than by checking the `update_id`s.

Consider the case where a channel is updated, leading to a
`ChannelMonitorUpdate` which completes asynchronously. The update
completes, but prior to the `ChannelManager` receiving the
`MonitorEvent::Completed` it generates a further
`ChannelMonitorUpdate`. This second update completes synchronously.
As a result, when the `MonitorEvent` is processed, the event's
`monitor_update_id` is the first update, but there are no updates
queued and the channel should be free to return to be unblocked.

Here we fix this by looking only at the `ChannelManager` update
queue, rather than the update_id of the `MonitorEvent`.

While we don't anticipate many users having both synchronous and
asynchronous persists in the same application, there isn't much
cost to supporting it, which we do here.
