Run CI on mac os only with go1.13 and on windows only on go1.14.
Speed up tests. Introduce --allow-parallel-runners.
Block on parallel run lock 5s instead of 60s.
Don't invalidate analysis cache for minor config changes.
Ensure that `unused` is always the last
in execution order. It can speed up packages loading
a bit.
Refactor enabled linters set to remove extra logging.

* test that demostrates that deadline is not working if comes from the config
* overriding timeout with deadline when only deadline is different from its default value
* tests were not passing. default value for Deadline, that now only comes from config, is 0. Plus static check is going to fail because of deprecated cfg used
* golangci should use the latest golangci-lint version, that is the one deprecating deadline in favour of timeout
* README updated - looks the ci config in this project is used to generate usage instructions.. great!
Run all linters per package. It allows unloading package data when it's
processed. It dramatically reduces memory (and CPU because of GC) usage.

Don't perform extra go env calls in go/packages.
Load only needed go env vars in golangci-lint.
Stay in sync by enabled analyzers in go vet: remove nilness and
atomicalign analyzers, add errorsas analyzer.
Don't build SSA for govet.
Standalone govet runs 25% faster than before. All runs can be 5-10% faster
than before.

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.

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.
1. Rename in a backward compatible way
2. Remove gosec default exclude list because gosec is already disabled
by default.
3. Warn about unmatched linter names in //nolint directives
4. Process linter names in //nolint directives in upper case
5. Disable gosec for golangci-lint in .golangci.yml
