[eclipselink-dev] Fixed Bug 236181 - OSGI: Update OSGI Manifest entries

[Tom Ware <tom.ware@xxxxxxxxxx>]

Patch can be found at: https://bugs.eclipse.org/bugs/show_bug.cgi?id=236181

- Changed our bundles to import dependencies as packages instead of bundles

patch was reviewed by Mitesh Meswani

Also
- Removed EJB and ANT from shipped bundles
- Added "uses" to jpa manifest for external dependencies

Tested with simple OSGi examples - more OSGi testing to come as part of a
separate work item.

Please let me know if these changes cause issues for you on Europa.  My initial 
testing worked, but things were a bit slow at first.
