This also updates the indirect rust-bitcoin dependency to 0.29.
Major changes are in the descriptors management:
- The rust-miniscript descriptors don't support raw hashes
within the pk_h() fragments, so we don't need all the boutique
management for this.
- The key translator API changed.
- We now take a u16 for the timelock instead of our previous
checks. This was inspired by the new rust-bitcoin Sequence
type.
- We now take a path instead of just a derivation index in
DerivedKey. We might use paths after all...
As for rust-bitcoin it's just a few nits:
- No more 'global' field on PSBTs (yay)
- Couple more trait derivation on types
- Some APIs were renamed.
Hence add a 'spend_block_height' field to the 'coin' column in the
SQLite implementation. This also contains a couple cleanups, as well as
a fix (we were still checking if the blockheight was > 1).
I initially wanted to have a bridge table between the 'coins' and
'spend_transactions' table as we do in revaultd. But let's not optimize
to early, we'll see if/when we need it.
This also implements a simple JSONRPC server sanity check
And introduces a new tmp_dir() test utility, that i didn't have the courage to split from this commit
