go.mod, vendor: update (#3358)

* go.mod, vendor: remove unnecessary dependencies

Commands:
1. go mod tidy
2. go mod vendor

* go.mod, vendor: update cloud.google.com/go

Commands:
1. go get -u cloud.google.com/go
2. go mod tidy
3. go mod vendor

* go.mod, vendor: update cloud.google.com/*

Commands:
1. go get -u cloud.google.com/storage cloud.google.com/logging
2. go mod tidy
3. go mod vendor

* go.mod, .golangci.yml, vendor: update *lint*

Commands:
1. go get -u golang.org/x/tools github.com/golangci/golangci-lint@v1.47.0
2. go mod tidy
3. go mod vendor
4. edit .golangci.yml to suppress new errors (resolved in the same PR later)

* all: fix lint errors

hash.go: copy() recommended by gosimple
parse.go: ent is never nil
verifier.go: signal.Notify() with unbuffered channel is bad. Have no idea why.

* .golangci.yml: adjust godot rules

check-all is deprecated, but still work
if you're hesitating too - I'll remove this commit

-# Dots
-
-Implements the wildcard file matching in Go used by golint, go test etc.
-
-## Usage
-
-```go
-import "github.com/mgechev/dots"
-
-func main() {
-  result, err := dots.Resolve([]string{"./fixtures/..."}, []string{"./fixtures/foo"})
-  for _, f := range result {
-    fmt.Println(f);
-  }
-}
-```
-
-If we suppose that we have the following directory structure:
-
-```text
-├── README.md
-├── fixtures
-│   ├── bar
-│   │   ├── bar1.go
-│   │   └── bar2.go
-│   ├── baz
-│   │   ├── baz1.go
-│   │   ├── baz2.go
-│   │   └── baz3.go
-│   └── foo
-│       ├── foo1.go
-│       ├── foo2.go
-│       └── foo3.go
-└── main.go
-```
-
-The result will be:
-
-```text
-fixtures/bar/bar1.go
-fixtures/bar/bar2.go
-fixtures/baz/baz1.go
-fixtures/baz/baz2.go
-fixtures/baz/baz3.go
-```
-
-`dots` supports wildcard in both - the first and the last argument of `Resolve`, which means that you can ignore files based on a wildcard:
-
-```go
-dots.Resolve([]string{"github.com/mgechev/dots"}, []string{"./..."}) // empty list
-dots.Resolve([]string{"./fixtures/bar/..."}, []string{"./fixture/foo/...", "./fixtures/baz/..."}) // bar1.go, bar2.go
-```
-
-## Preserve package structure
-
-`dots` allow you to receive a slice of slices where each nested slice represents an individual package:
-
-```go
-dots.ResolvePackages([]string{"github.com/mgechev/dots/..."}, []string{})
-```
-
-So we will get the result:
-
-```text
-[
-  [
-    "$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/bar/bar1.go",
-    "$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/bar/bar2.go"
-  ],
-  [
-    "$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/baz/baz1.go",
-    "$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/baz/baz2.go",
-    "$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/baz/baz3.go"
-  ],
-  [
-    "$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/foo/foo1.go",
-    "$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/foo/foo2.go",
-    "$GOROOT/src/github.com/mgechev/dots/fixtures/dummy/foo/foo3.go"
-  ],
-  [
-    "$GOROOT/src/github.com/mgechev/dots/fixtures/pkg/baz/baz1.go",
-    "$GOROOT/src/github.com/mgechev/dots/fixtures/pkg/baz/baz2.go"
-  ],
-  [
-    "$GOROOT/src/github.com/mgechev/dots/fixtures/pkg/foo/foo1.go",
-    "$GOROOT/src/github.com/mgechev/dots/fixtures/pkg/foo/foo2.go"
-  ],
-  [
-    "$GOROOT/src/github.com/mgechev/dots/fixtures/pkg/foo/bar/bar1.go"
-  ]
-]
-```
-
-This method is especially useful, when you want to perform type checking over given package from the result.
