Create safe mode where session concurrent access is checked
-----------------------------------------------------------

                 Key: JBMESSAGING-752
                 URL: http://jira.jboss.com/jira/browse/JBMESSAGING-752
             Project: JBoss Messaging
          Issue Type: Task
            Reporter: Tim Fox
         Assigned To: Tim Fox
             Fix For: 1.2.1


As per JMS spec, a JMS session is supposed to be only accessed from one thread at a time.

This is so the implementor does not have to synchronize access which might degrade performance.

However, users are often unaware of this and use the session concurrent by multiple threads, resulting in subtle or hard to identify bugs.

We should create a "safeMode", where if enabled, concurrent access is checked.

safeMode should be turned on for development and off for production, so no performance penalty is incurred in production.
