Add `stylecheck` to our list of lints, since it got separated out from
`staticcheck`. Fix the way we configure both to be clearer and not
rely on regexes.
Additionally fix a number of easy-to-change `staticcheck` and
`stylecheck` violations, allowing us to reduce our number of ignored
checks.
Part of #5681
Running an older version (v0.0.1-2020.1.4) of `staticcheck` in
whole-program mode (`staticcheck --unused.whole-program=true -- ./...`)
finds various instances of unused code which don't normally show up
as CI issues. I've used this to find and remove a large chunk of the
unused code, to pave the way for additional large deletions accompanying
the WFE1 removal.
Part of #5681
If a berror with suberrors is being wrapped then we must marshal the
suberrors as JSON and include this data in the RPC metadata trailer that
also carries the berror type. When unwrapping metadata with JSON
suberrors they should be unmarshalled into the returned berror's
suberrors.
