In general, a validating signer may be under a different operational
environment than the node, and therefore may have a different
source of on-chain data. The signer may therefore temporarily disagree
on whether a funding or splice transaction is locked (buried).
We would like to ensure agreement between the signer and the
node on how to progress a channel's state.
The following message are added to provide a solution:
- `check_outpoint(outpoint) -> bool` - check if the signer agrees that a funding candidate outpoint is buried
- `lock_outpoint(outpoint)` - change the funding/splice state to locked

The nomenclature confusion mean that we were ANDING a capability
with a message number (29) which always returned non-zero. We really
do need a new capability which we can hand to channeld to make these
splice txs.

I obviously like the word "capabilities" since I reused it to refer
to the HSM's overall features :(
