8a7dd2f9b8 Fix peer_handler message serialization
Fixes a bug introduced in 3e89106163
where messages were being encoded with their size instead of their
type.
Also utilizes the new size_hinting in peer_handler

8322c756cb Stop checking size > 64KB in serialization
This removes a bunch of potentially new error handling in writers
and the checks were kinda useless anyway - in normal operation we
unwrap()ed anyway, and we're gonna want to use the serializtion
framework for ChannelMonitor/ChannelManager serialization, which
may generate things larger than 64KB anyway.

4bcf00e5b8 Clarify update_fail/fulfill_htlc holding cell allowed Errs
Specifically, there really should be no Errs, but in case there is
some case where duplicate HTLC removes are possible, return
IgnoreError and debug_assert to see if fuzzing can find them.

5ef88cea34 Do not fail-backwards LocalAnnounced HTLCs upon force-close.
This is completely unsafe as we have provided the remote side with
a commitment_signed which they can broadcast, including the HTLC
transaction, and then could claim it on-chain after we've failed it
backwards!

66d5d764aa Clean up and clarify tx broadcast checks in channelmonitor tests
This effecitlvey reverts the refactors in 383bd90a48,
however keeps the actully new test code.

It also writes documentation for the super confusing tx test func
and makes it a bit less permissive.

27d5a3a94f Optimize check_spend_remote HTLC a tad by avoiding indirections
Instead of hopping a pointer, we're only ever going to return one
Transaction at max, so skip the Vec. Also avoid
re-pubkey-converting the revocation key.

d7ed4c63e7 Correct MAX_BUF_SIZE in serialization
I think this might have been my fault due to faulty review
feedback, but fuzzer caught trivial crash here where you try to
send a ping message larger than 16KB (but smaller than the
max-length 64KB) and you crash as message serialization is unwrap()
