In this commit, we update new Taproot related TLVs (nonces, partial sig, sig with nonce, etc). Along the way we were able to get rid of some boiler plate, but most importantly, we're able to better protect against API misuse (using a nonce that isn't initialized, etc) with the new options API. In some areas this introduces a bit of extra boiler plate, and where applicable I used some new helper functions to help cut down on the noise. Note to reviewers: this is done as a single commit, as changing the API breaks all callers, so if we want things to compile it needs to be in a wumbo commit.
channeldb
The channeldb implements the persistent storage engine for lnd and
generically a data storage layer for the required state within the Lightning
Network. The backing storage engine is
boltdb, an embedded pure-go key-value store
based off of LMDB.
The package implements an object-oriented storage model with queries and mutations flowing through a particular object instance rather than the database itself. The storage implemented by the objects includes: open channels, past commitment revocation states, the channel graph which includes authenticated node and channel announcements, outgoing payments, and invoices
