* dbus/dbus-server-socket.c (_dbus_server_new_for_tcp_socket): implemented returning tcp port. Skipping port parameter and non integer port values in config <listen> statement needs more effort.
* dbus/dbus-sysdeps-unix.c, dbus/dbus-sysdeps-win.c (_dbus_listen_tcp_socket): return the real used tcp port.
* bus/dbus-daemon.1.in: added <listen> tcp examples

Example: <listen>unix:path=/tmp/foo</listen>
.PP
+Example: <listen>tcp:host=localhost,port=1234</listen>
+
+.PP
If there are multiple <listen> elements, then the bus listens
on multiple addresses. The bus will pass its address to
started services or other interested parties with
the last address given in <listen> first. That is,
apps will try to connect to the last <listen> address first.
+.PP
+A special case is using a port number of zero which means to
+pick up a random free port. The real used port number could be retrieved
+by using the --print-address command line parameter.
+
+.PP
+Example: <listen>tcp:host=localhost,port=0</listen>
