Make JDBC store resilient on broker sequence id order
-----------------------------------------------------

                 Key: AMQ-2594
                 URL: https://issues.apache.org/activemq/browse/AMQ-2594
             Project: ActiveMQ
          Issue Type: Improvement
    Affects Versions: 5.3.0
            Reporter: Dejan Bosanac
            Assignee: Dejan Bosanac
             Fix For: 5.3.1, 5.4.0


Currently if the message is sent in a transaction, there's a chance that 
messages are added to the cursor out of order (regarding broker seq id). The 
problem with JDBC store is that it does message recovery based on this seq id, 
which can lead to all kind of problems (such as orphaned messages in the 
database).

The solution is to refactor JDBC store to use its own seq generator for 
recovering purposes and replace broker seq id, with message id for all other 
operations
