Enable staticcheck's SA1019 check in golangci-lint so deprecated
identifiers are caught in CI.
Replace deprecated standard library and bbolt APIs with their current
equivalents. Keep intentional compatibility reads and writes of
deprecated Loop RPC fields behind narrow nolint annotations, because
older clients and persisted liquidity parameters still depend on those
fields.
In successive commits we want to access lnrpc specifc methods
and objects, so here we import github.com/lightningnetwork/lnd v0.20.1-beta
into looprpc and update relevant versions.
This commit adds a module for a finite state machine. The goal of the
module is to provide a simple, easy to use, and easy to understand
finite state machine. The module is designed to be used in future
loop subsystems. Additionally a state visualizer is provided to
help with understanding the state machine.
This commit fixes outstanding linter issues, that we're not found by
running `make lint` locally. The linter issues were found by running
`docker run -v $(pwd):/build loop-tools golangci-lint run --whole-files`
I added the `revive` to the excludes as it would be to much of a
refactor and IMO seems unneccesary. E.g.
`interface.go:222:6: exported: type name will be used as
loop.LoopInTerms by other packages, and that stutters; consider
calling this InTerms (revive)`. I think `loop.LoopInTerms` is fine.
