80aa4f20a9 Make channel open confs configurable (and change from 12 to 6) 
This fixes compatibility with c-lightning etc as they won't accept
a minimum_depth of 12.

50e16c9573 Rewrite Channel resend tracking to make it much more reliable 
Resending revoke_and_ack and commitment_signed (+update) messages
after monitor-update-failure or disconnection has been a highly
unreliable part of our codebase for some time (as evidenced by the
number of bugs caught in the chanmon_fail_consistency fuzz target).
This is due to its rather ad-hoc nature and tracking/behavior which
consists of checking a number of different flags to try to deduce
which messages were/were not delivered and go from there. Instead,
this commit rewrites it to simply keep track of the order messages
were generated originally, as we always resend in the
originally-generated order.

I'm anticipating this will be way more robust than the old code, in
addition to its simplicity.

29ed3e227f Move fail_reason into OutboundHTLCState states 
This should probably have happened when we moved most state into
the state enums themselves, but specifically forcing awareness of
the removed/not removed state would have prevented me from
introducing a bug in the first version of an upcoming reserve-value
patch.

bf26056c8a Fix holding cell freeing in case we fail to add some HTLC 
Previously, if we went to free the holding cell HTLC updates, and
adding one failed as we hit our outbound HTLC limit (or in-flight
value limit), we would not send a commitment_signed, leaving us in
an invalid state. We first fix that bug, and then refuse to add
things to our holding cell once we reach our limits considering the
holding cell, as we shouldn't have multiple commitment dance rounds
worth of HTLCs in the holding cell anyway.

1bc190c760 Drop pending outbound messages on peer disconnection 
This shouldn't be required, but it may help prevent some downstream
race conditions due to clients not sending message events quickly
enough and trying to send stale messages before new
channel_reestablish messages.

985688852b Fix AwaitingRAA on RAA receipt when monitor updating had failed 
This fixes a rather subtle case handling RAAs when we don't
generate a response due to a previous monitor update failure, but
would otherwise send a CS response. We need to still set
AwaitingRemoteRevoke on the channl in question, but previously did
not. Found by chanmon_fail_consistency fuzz test with the failing
test converted and added manually.
