Go 1.17.2 fixes some miscompilation issues on amd64 and a runtime issue with timers.
While the upgrade is not strictly necessary for go-ethereum right now, it is still good
to be up-to-date.
The new linter version is built with go 1.17 and thus includes the go vet
check for mismatched +build and go:build lines.
Fortunately, no new warnings are reported with this update.
This new flag downloads a known version of Go and builds with it. This
is meant for environments where we can't easily upgrade the installed Go
version.
* .travis.yml: remove install step for PR test builders
We added this step originally to avoid re-building everything
for every test. go test has become much smarter in recent go
releases, so we no longer need to install anything here.
* build: use golangci-lint
This changes build/ci.go to download and run golangci-lint instead
of gometalinter.
