Revision 1355851

Refactoring for release, clean up and review new public api, sanity check and remove unnecessary methods.

Added dnsjava name service provider to handle reverse dns lookup and to provide concurrent dns lookups.

Updated reference-collections, these were updated to avoid calling hashCode during initialisation of Timed references and temporary referrers, this helped reduced SocketPermission.hashCode calls that caused reverse lookups and recursive permission checks that cause stack overflow in the CombinerSecurityManager.

Two tests are failling due to a change to ConcurrentPolicyFile, now only privileged domains are returned by getPermissions(CodeSource) and all other instances are diverted to the java.security.Policy superclass which returns an empty PermissionCollection this is to avoid checking permissions twice.

Failing tests:
