Improve efficiency of RegionManagerImpl.getRegion
-------------------------------------------------

                 Key: JBCACHE-1536
                 URL: https://jira.jboss.org/jira/browse/JBCACHE-1536
             Project: JBoss Cache
          Issue Type: Task
      Security Level: Public (Everyone can see)
          Components: Eviction
            Reporter: Brian Stansberry
            Assignee: Brian Stansberry


A profiling run showed almost 37 ms for 22 invocations.

Fqns were 

/SFSB/container-name/bucketInt/sessionId

Region names were /SFSBcontainer-name

The trick in JBC 1.x (I believe by genman) of tracking the max length of registered regions and starting searches at that depth should be restored.  The lookups also do this:

      if (regionsRegistry.containsKey(fqnToUse))
      {
         Region r = regionsRegistry.get(fqnToUse);

which means 2 searches per request.
