net/url, net/http: reject control characters in URLs

This is a more conservative version of the reverted CL 99135 (which
was reverted in CL 137716)

The net/url part rejects URLs with ASCII CTLs from being parsed and
the net/http part rejects writing them if a bogus url.URL is
constructed otherwise.
