DefaultMetadata changes for revisions 24924:24925

This commit propagates an interface name change which was done in GeoAPI. There is no way such change could be done differently, since not renaming the uses of that interface cause a compilation error.

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.
