In this commit, we update the Sig type to support ECDSA and schnorr signatures. We need to do this as the HTLC signatures will become schnorr sigs for taproot channels. The current spec draft opts to overload this field since both the sigs are actually 64 bytes in length. The only consideration with this move is that callers need to "coerce" a sig to the proper type if they need schnorr signatures.
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
