Go: x/net: The httplex package was moved by googlegit

What version of Go are you using (go version)?

go version go1.9.2 linux/amd64

Does this issue reproduce with the latest release?

It's doesn't matter to the latest version.

What operating system and processor architecture are you using (go env)?

What did you do?

1. go get -u golang.org/x/net/lex/httplex
2. the result with above step:
   [root@host-172-19-146-103 netplugin]# go get golang.org/x/net/lex/httplex
   package golang.org/x/net/lex/httplex: cannot find package "golang.org/x/net/lex/httplex" in any of:
   /usr/local/go/src/golang.org/x/net/lex/httplex (from $GOROOT)
   /root/contiv/src/golang.org/x/net/lex/httplex (from $GOPATH)

3. check the package in the googlegit, and we found the commit:
   lex/httplex, http/httpguts: merge the httplex package into httpguts

   httplex was the original package name for shared code between net/http
   and x/net/http2, but its name was too specific, and http/httpguts was
   added later for other shared code.

   We discussed merging httplex into httpguts at the time, but it didn't
   happen earlier. This finishes the move.

   Updates golang/go#23908
   The package name already has been move to the http/httpguts/.
   So that, wo can not found them in the master branch.

4. I suggest that modify the import path in four files.

   17 "golang.org/x/net/http2/hpack"

What did you expect to see?

go get normal
