Subject: QPID-1567: Initial support for asynchronous queue state replication

* Added QueueEvents class with per broker instance
* Modified qpid::broker::Queue to notify QueueEvents of enqueues and dequeues (based on configuration)
* Added replication subdir containing two plugins:
  - an event listener that registers with QueueEvents and creates messages representing received
    events on a replication queue
  - a custom exchange type for processing messages of the format created by the listener plugin
* Added new option for controlling event generation to qpid::client::QueueOptions
* Added new queue option to qpid-config script for the same
