Fix#324, relates #314
1. Update gocritic to the latest version
2. Use proper gocritic checkers repo, old repo was archived
3. Get enabled by default gocritic checks in sync with go-critic: don't
enable performance, experimental and opinionated checks by default
4. Support of `enabled-tags` options for gocritic
5. Enable almost all gocritic checks for the project
6. Make rich debugging for gocritic
7. Meticulously validate gocritic checks config
Also do following improvements:
- show proper sublinter name for megacheck sublinters
- refactor and make more simple and robust megacheck
merging/optimizing
- improve handling of unknown linter names in //nolint directives
- minimize diff of our megacheck version from the upstream,
https://github.com/golang/go/issues/29612 blocks usage of the upstream
version
- support the new `stylecheck` linter
- improve tests coverage for megacheck and nolint related cases
- update and use upstream versions of unparam and interfacer instead of forked
ones
- don't use golangci/tools repo anymore
- fix newly found issues after updating linters
Also should be noted that megacheck works much faster and consumes less
memory in the newest release, therefore golangci-lint works noticeably
faster and consumes less memory for large repos.
Relates: #314
Use go/packages instead of x/tools/loader: it allows to work
with go modules and speedups loading of packages with the help
of build cache.
A lot of linters became "fast": they are enabled by --fast now and
work in 1-2 seconds. Only unparam, interfacer and megacheck
are "slow" linters now.
Average project is analyzed 20-40% faster than before if all linters are
enabled! If we enable all linters except unparam, interfacer and
megacheck analysis is 10-20x faster!
Add support for the exclude and ignore flags of errcheck.
Note that, this commit depends on golangci/errcheck#1. We need
to merge it first, update vendors and only then merge this one.
