6856630: Restructure jaxp/jaxws repository

Sorry I'm so slow on this, ...

I'm looking at updating the jaxp bundle. The webrev is:

Updated jaxp source bundle, and complete removal of anything
that would use the original source. The final changeset will also
delete the jaxp/src directory so we never accidently use it.
It also adds a md5 checksum check on the bundle in the ant script,
a property value contains the expected checksum.

I'm not done, so I could add more if you want me to add the changes
mentioned here... The merge should be trivial.

One snag is that I plan on pushing this to the TL forest so that
the TL integrator (Tim Bell) can get the appropriate tests done
on the jaxp changes. In the future jaxp changes will probably
be going through the TL area.

...  a few more comments below...

I'm ok with ALT_DROPS_DIR and drops.dir.

I will look into that. You have convinced me. ;^)

Ah... so my checksum logic in the ant script will serve as a
double check.

Unless you are changing the bundles and rebundling them...
nobody does that, ...  do they???
Ah, if they do, they would need to change the property value
holding the checksum.
