Do not execute the default_value expr until we need it in TLV deser

This fixes an insta-panic in `ChannelMonitor` deserialization where
we always `unwrap` a previous value to determine the default value
of a later field. However, because we always ran the `unwrap`
before the previous field is read, we'd always panic.

The fix is rather simple - use a `OptionDeserWrapper` for
`default_value` fields and only fill in the default value if no
value was read while walking the TLV stream.

The only complexity comes from our desire to support
`read_tlv_field` calls that use an explicit field rather than an
`Option` of some sort, which requires some statement which can
assign both an `OptionDeserWrapper<T>` variable and a `T` variable.
We settle on `x = t.into()` and implement `From<T> for
OptionDeserWrapper<T>` which works, though it requires users to
specify types explicitly due to Rust determining expression types
prior to macro execution, completely guessing with no knowlege for
integer expressions (see

Fix spurious panic on bogus funding txn that confirm and are spent

In c02b6a3807488e1943d79792c5ac0ee52530b971 we moved the
`payment_preimage` copy from inside the macro which only runs if we
are spending an output we know is an HTLC output to doing it for
any script that matches our expected length. This can panic if an
inbound channel is created with a bogus funding transaction that
has a witness program of the HTLC-Success/-Offered length but which
does not have a second-to-last witness element which is 32 bytes.

Luckily this panic is relatively simple for downstream users to
work around - if an invalid-length-copy panic occurs, simply remove
the ChannelMonitor from the bogus channel on startup and run
without it. Because the channel must be funded by a bogus script in
order to reach this panic, the channel will already have closed by
the time the funding transaction is spent, and there can be no
local funds in such a channel, so removing the `ChannelMonitor`
wholesale is completely safe.

In order to test this we have to disable an in-line assertion that
checks that our transactions match expected scripts which we do by
checking for the specific bogus script that we now use in
`test_invalid_funding_tx`.

In the "running with outdated state but ChannelMonitor(s) and

Don't fail HTLCs in revoked commitment txn until we spend them

When we see a counterparty revoked commitment transaction on-chain
we shouldn't immediately queue up HTLCs present in it for
resolution until we have spent the HTLC outputs in some kind of
claim transaction.

In order to do so, we first have to change the
`fail_unbroadcast_htlcs!()` call to provide it with the HTLCs which
are present in the (revoked) commitment transaction which was
broadcast. However, this is not sufficient - because all of those
HTLCs had their `HTLCSource` removed when the commitment
transaction was revoked, we also have to update
`fail_unbroadcast_htlcs` to check the payment hash and amount when
the `HTLCSource` is `None`.

Somewhat surprisingly, several tests actually explicitly tested for
the old behavior, which required amending to pass with the new
changes.

Finally, this adds a debug assertion when writing `ChannelMonitor`s
to ensure `HTLCSource`s do not leak.

Correct handling of reorg'd-out revoked counterparty transactions

Previously, while processing a confirmed revoked counterparty
commitment transaction, we'd populate `OnchainEvent`s for live
HTLCs with a `txid` source of the txid of the latest counterparty
commitment transactions, not the confirmed revoked one. This meant
that, if the user is using `transaction_unconfirmed` to notify us
of reorg information, we'd end up not removing the entry if the
revoked commitment transaction was reorg'd out. This would
ultimately cause us to spuriously resolve the HTLC(s) as the chain
advanced, even though we were doing so based on a now-reorged-out
transaction.

Luckily the fix is simple - set the correct txid in the
`OnchainEventEntry`. We also take this opportunity to update
logging in a few places with the txid of the transaction causing an
event.
