Use performant order collections in TransactionEntry
----------------------------------------------------

                 Key: JBCACHE-874
                 URL: http://jira.jboss.com/jira/browse/JBCACHE-874
             Project: JBoss Cache
          Issue Type: Task
      Security Level: Public (Everyone can see)
            Reporter: Brian Stansberry
         Assigned To: Brian Stansberry
             Fix For: 1.4.1.GA, 2.0.0.ALPHA2


If multiple locks are associated with a TransactionEntry, it's highly non-performant, since for each addition the class does a contains() check on a LinkedList.  We should replace the LinkedList fields with LinkedHashSet.  With that, the contains test can be removed all together, as a 2nd add of the same object to a LinkedHashSet has no impact on the collection ordering.

See forum post for profiling info on the current impl.
