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.
This commit adds a new bucket to save liquidity parameters. We've
skipped the serialization and deserialization implementations here and
leave them to be handled by the liquidity package.
This addresses an issue where using a sweep confirmation target greater
than the default would result in most cases not revealing the preimage
due to the default confirmation target yielding a higher fee than the
max miner fee backed by the confirmation target provided.
This commit adds the required code to persist loop in swaps. It also
introduces the file loop.go to which shared code is moved.
Sharing of contract serialization/deserialization code has been
reverted. The prepay fields do not apply to loop in, but were part of
the shared contract struct. Without also adding a migration, it wouldn't
be possible to keep the shared code.
In general it is probably more flexible to keep the contract
serialization code separated between in and out swaps.
