go.net/html: move exp/html and exp/html/atom here to the go.net
sub-repo.
It's a straight copy, except for these modifications:
* "exp/html" and "exp/html/atom" imports were renamed, and
* the "TODO... When this package moves out of exp" comment was
deleted from atom/atom.go.
The matching change is at https://golang.org/cl/7317043
