Dynamic allocation of mountpoint names is not done.

When using a native icecast source client (edcast can be configured for 
that) then a mountpoint is supplied by the source client and icecast 
uses that to lookup the authentication details and any other mount 

When using a shoutcast style source client, then it does not send a 
mountpoint so icecast assumes one based upon the incoming port (actually 
2 sequential ports). 2.3.1 only allowed one of these clients to connect 
at any one time (and used the global shoutcast-mount setting and 2 
listen-socket sections), but 2.3.2 allows for several as long as they 
are on different ports (shoutcast-mount in the listen-socket). eg
