6856630: Restructure jaxp/jaxws repositories

Goal is to ease the jaxp and jaxws integration into jdk7.
The JAXP or JAXWS teams would make the jdk7 source drop bundles available,
and integration into jdk7 would involve the modifications of
some properties in jaxp/build.properties to use different drop bundles.

   * 'ant source' populates the drop source and would be run prior to
     the creation of larger source bundles for openjdk7 and jdk7.

   * Test bundle specifics and how the tests are run are TBD

   * Original source is still in the "src/" directory and after
     some soak time will be deleted from the repository or moved aside.

   * Formal builds can use ALT_JAX*_SOURCE_BUNDLE to select the bundle.
