Merged BRANCHES/DEV/mward/head_cachestats to HEAD:
89575: ACE-3327: Work In Progress. TX cache statistics. 89642: ACE-3327: Exposes statistics through JMX. Adds hit ratio. 89649: ACE-3327: Added "@since 5.0" to new classes. 89691: ACE-3327: improved TransactionalCache stats tests. 89743: ACE-3327: fixed lack of thread safety for InMemoryCacheStatistics. 89752: ACE-3327: now possible to disable/enable tx cache statistics per-cache with properties. git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@89798 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
