AbstractElement changes for revisions 24924:24925

This commit propagates a method signature change which was done in GeoAPI. Reverting this commit cause a compilation error, which is resolved by modifying the method signature as in this commit. Those signatures can only be the same, however the method bodies are different in Geotk/SIS.

Action: all contributions forced by changes in GeoAPI interfaces (mostly import statements and method signatures) have been rewritten from scratch by creating an empty Java class implementing the interface, clicking on the "Implement all abstract methods" contextual menu in NetBeans, removing the <? extends> part in parameterized type of collections, adding the synchronized keyword (for now) and finally adding the corresponding private fields. This action has been committed in the Apache SIS JDK7 branch at revision 1458238.
