6856630: Restructure jaxp/jaxws repository

[Kelly O'Hair]

This 6856630 change has been integrated into the build
forest jaxp and jaxws repositories:

http://hg.openjdk.java.net/jdk7/build/jaxws/rev/ae2bec597586
http://hg.openjdk.java.net/jdk7/build/jaxp/rev/534e23823a1b

Assuming we get successful test builds of the build forest, these
changes will get integrated into the jdk7 master forest.

Notes:
   * The jaxws (and jaf) and jaxp sources have been extracted and
     put into separate source zip files. These zip files represent
     the source deliveries into the jdk7 project. Selection of
     the bundles is determined by the properties in the files
     jax*/jax*.properties and jax*/build-defs.xml.
     The current 3 source drop bundles are:
       jdk7-jaf-2009_08_28.zip
       jdk7-jaxp-2009_08_28.zip
       jdk7-jaxws-2009_08_28.zip
     If not found in the /java/devtools/share/jdk7-drops directory,
     the ant scripts will look for them at
       http://kenai.com/projects/jdk7-drops/downloads
     a temporary site for now until the JAX* teams engage.

   * The original jaxp/src and jaxws/src files are still there,
     but should not be used unless the drop source bundles are
     unavailable (currently the drop bundles contain the exact
     same files). A warning will be issued if they are used.
     Eventually the original jaxp/src and jaxws/src files will
     be deleted from the jdk7 repositories.

   * 'ant source' or 'cd make && make source' will get the drop
     bundles and populate the drop source area. But this should
     happen automatically.

Please ask questions, this is kind of a big change and anything
can go wrong, please let me know if there are problems.
