Ken Sedgwick 485cabb25e splice: Add hsmd_check_outpoint and hsmd_lock_outpoint
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
