Spin off src/library/scala/xml to src/xml/scala/xml.

Summary:
  - Remove the last vestiges of xml from Predef and Contexts.
  - Change build to compile scala.xml to scala-xml.jar.
  - Deploy scala-xml module to maven.
  - Update partest accordingly.

Note:
An older compiler cannot use the new standard library to
compile projects that use XML. Thus, skipping locker will
break the build until we use 2.11.0-M4 for STARR.

In the future build process, where we drop locker,
we would have to release a milestone that supports the old
and the new approach to xml. As soon as we'd be using that
new milestone for starr, we could drop support for the old approach.
