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
