Subject: [PATCH] [release-branch.go1.8] doc: hide video and share if being
 served from CN

In the case where requests are coming from mainland China, hide
links to locations that are blocked and functionality that is
not permitted.

Additionally, some very small cleanup of the JS.

This change requires https://go-review.googlesource.com/c/52873
