rtsptransport: support single port for client_port and server_port

Browse source 
This is explicitly specified as valid in the RFC, where the
syntax for both parameters is:

";" "client_port" "=" port [ "-" port ]
";" "server_port" "=" port [ "-" port ]

This is useful for applications where RTCP is either not necessary
or not possible.
