The previous implementation used per-socket TCP keepalive options wrong. For example, it used another level socket option to control TCP and it didn't use TCP_KEEPINTVL option when possible. Fixes #8683. Fixes #8701. Update #8679 LGTM=iant R=golang-codereviews, iant CC=golang-codereviews https://golang.org/cl/136480043
