Fail HTLCs which were removed from a channel but not persisted
When a channel is force-closed, if a `ChannelMonitor` update is
completed but a `ChannelManager` persist has not yet happened,
HTLCs which were removed in the latest (persisted) `ChannelMonitor`
update will not be failed even though they do not appear in the
commitment transaction which went on chain. This is because the
`ChannelManager` thinks the `ChannelMonitor` is responsible for
them (as it is stale), but the `ChannelMonitor` has no knowledge of
the HTLC at all (as it is not stale).
The fix for this is relatively simple - we need to check for this
specific case and fail back such HTLCs when deserializing a
`ChannelManager`

Avoid attempting to forward to a closed chan on stale-data reload
If, after forwarding a payment to our counterparty, we restart with
a ChannelMonitor update having been persisted, but the
corresponding ChannelManager update was not persisted, we'll still
have the forwarded HTLC in the `forward_htlcs` map on start. This
will cause us to generate a (spurious) `PendingHTLCsForwardable`
event. However, when we go to forward said HTLC, we'll notice the
channel has been closed and leave it up to the `ChannelMontior` to
finalize the HTLC.
This is all fine today - we won't lose any funds, we'll just
generate an excess forwardable event and then fail to forward.
However, in the future when we allow for forward-time channel
changes this could break. Thus, its worth adding tests for this
behavior today, and, while we're at it, removing the spurious
forwardable HTLCs event.

Expose the full set of outbound HTLCs from a `ChannelMonitor`
This expands the outbound-HTLC-listing support in `ChannelMonitor`
to include not only the set of outbound HTLCs which have not yet
been resolved but to also include the full set of HTLCs which the
`ChannelMonitor` is currently able to to or has already finalized.
This will be used in the next commit to fail-back HTLCs which were
removed from a channel in the ChannelMonitor but not in a Channel.
Using the existing `get_pending_outbound_htlcs` for this purpose is
subtly broken - if the channel is already closed, an HTLC fail may
have completed on chain and is no longer "pending" to the monitor,
but the fail event is still in the monitor waiting to be handed
back to the `ChannelMonitor` when polled.

Accept feerate increases even if they aren't high enough for us
LND nodes have very broken fee estimators, causing them to suggest
feerates that don't even meet a current mempool minimum feerate
when fees go up over the course of hours. This can cause us to
reject their feerate estimates as they're not high enough, even
though their new feerate is higher than what we had already (which
is the feerate we'll use to broadcast a closing transaction). This
implies we force-close the channel and broadcast something with a
feerate lower than our counterparty was offering.
Here we simply accept such feerates as they are better than what we
had. We really should also close the channel, but only after we
get their signature on the new feerate. That should happen by
checking channel feerates every time we see a new block so is
orthogonal to this code.
Ultimately the fix is anchor outputs plus package-based relay in
Bitcoin Core, however we're still quite some ways from that, so
worth needlessly closing channels for now.

Offer features for BOLT 12
The offer message in BOLT 12 contains a features TLV record. Add a
corresponding OfferFeatures type where the length is not included in the
serialization as it would be redundant with the record length.
Otherwise, define the features to be the same as InvoiceFeatures.

Consider `channel_id`s in `short_to_chan_info` as unguaranteed

Add missing break when scoring a path with a missing channel
If we send payments over a path where a channel ended up being
closed, we'll remove it before we call
`ProbabilisticPaymentScorer::payment_path_failed`. This should be
fine, except that `payment_path_failed` does not break out of its
scoring loop if a channel is missing, causing it to assign a
minimum available-liquidity of the payment amount even to channels
which our attempt never arrived at.
The fix is simple - add the missing check and break.
