inbound channel on which we received a forwarded payment has been
closed, but then ignores it in favor of looking at the fee in the
event. While this is generally correct, in cases where we process
an event after a channel was closed, which was generated before a

Block the mon update removing a preimage until upstream mon writes

When we forward a payment and receive an `update_fulfill_htlc`
message from the downstream channel, we immediately claim the HTLC
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.

This is safe as long as `ChannelMonitorUpdate`s complete in the
order in which they are generated, but of course looking forward we
want to support asynchronous updates, which may complete in any
order.

Thus, here, we enforce the correct ordering by blocking the
downstream `ChannelMonitorUpdate` until the upstream one completes.
Like the `PaymentSent` event handling we do so only for the
`revoke_and_ack` `ChannelMonitorUpdate`, ensuring the
preimage-containing upstream update has a full RTT to complete
before we actually manage to slow anything down.

Include PaymentId in payer metadata

When receiving a BOLT 12 invoice originating from either an invoice
request or a refund, the invoice should only be paid once. To accomplish
this, require that the invoice includes an encrypted payment id in the
payer metadata. This allows ChannelManager to track a payment when
requesting but prior to receiving the invoice. Thus, it can determine if
the invoice has already been paid.

Drop dep `tokio`'s `io-util` feat as it broke MSRV and isn't useful

We use `tokio`'s `io-util` feature to provide the
`Async{Read,Write}Ext` traits, which allow us to simply launch a
read future or `poll_write` directly as well as `split` the
`TcpStream` into a read/write half. However, these traits aren't
actually doing much for us - they are really just wrapping the
`readable` future (which we can trivially use ourselves) and
`poll_write` isn't doing anything for us that `poll_write_ready`
can't.

Similarly, the split logic is actually just `Arc`ing the
`TcpStream` and busy-waiting when an operation is busy to prevent
concurrent reads/writes. However, there's no reason to prevent
concurrent access at the stream level - we aren't ever concurrently
writing or reading (though we may concurrently read and write,
which is fine).

Worse, the `io-util` feature broke MSRV (though they're likely to
fix this upstream) and carries two additional dependencies (only
one on the latest upstream tokio).

Thus, we simply drop the dependency here.

Fixes #2527.

Fix flaky aggregated HTLC revocation test.

Releasing write locks in between monitor updates
requires storing a set of cloned keys to iterate
over. For efficiency purposes, that set of keys
is an actual set, as opposed to array, which means
that the iteration order may not be consistent.

The test was relying on an event array index to
access the revocation transaction. We change that
to accessing a hash map keyed by the txid, fixing
the test.

Release write lock between monitor update iterations.

Previously, updating block data on a chain monitor

completed.

Now, we instead acquire it on each iteration,
fixing #2470.
