The go directive is now at 1.23.0, so the go1.7 and go1.9 build constraints are guaranteed to always be satisfied, and their inverse will never be satisfied. Delete all the dead code and merge everything that's left in a single context.go file. Also update docs to match the upstream context package. For golang/go#49506.
