The repository github.com/myitcv/gobin has already been archived,
and the `go install` command accepts arguments with version suffixs
starting from 1.16 (for example, go install example.com/cmd@v1.0.0).
So there is no reason to continue to use gobin.
Replace ./scripts/install_tool.sh with `gobin`, such that we have
consistent handling for all tools needed for build and consistent
versioning within ./tools/mod/go.mod.
Side changes:
- Expose /scripts/fix.sh that fixes formatting and bom across modules
- Expose *.sh variants of scripts like build and ./test (first step
towards replacement).
- Make stderr output of commands explicit and make commands use
different color than callouts.
Update to Go 1.12.5 testing. Remove deprecated unused and gosimple
pacakges, and mask staticcheck 1006. Also, fix unconvert errors related
to unnecessary type conversions and following staticcheck errors:
- remove redundant return statements
- use for range instead of for select
- use time.Since instead of time.Now().Sub
- omit comparison to bool constant
- replace T.Fatal and T.Fatalf in tests with T.Error and T.Fatalf respectively because the goroutine calls T.Fatal must be called in the same goroutine as the test
- fix error strings that should not be capitalized
- use sort.Strings(...) instead of sort.Sort(sort.StringSlice(...))
- use he status code of Canceled instead of grpc.ErrClientConnClosing which is deprecated
- use use status.Errorf instead of grpc.Errorf which is deprecated
