Remove trying to specify or track low level connections in this patch.


Summary (updated)
-------

One user can consume all connections to the broker as a denial of service 
attack. This patch provides command line limits to the number of connections 
made by an individual user or by a host computer.
 
The user is tracked by the connection user name and hosts are tracked by the 
client computer's IP address as seen in the connection's management ID. 

This code uses the broker::ConnectionObserver facility.

This patch does NOT time out lower level socket connections such as when a user 
telnets in to the qpid broker socket and then transfers no data. To effect this 
function requires the addition of a transport/socket observer facility similar 
to the ConnectionObserver or to have those functions built into the lower 
layers.

This code is added as part of the ACL plugin. If the ACL plugin is not loaded 
then the functions are unavaliable and there is zero performance impact. 
Individual tracking limits may be disabled by setting their AclOptions values 
to 0.


This addresses bug QPID-2616.
