roar_connectionref, roar_connectionunref - change reference counter for RoarAudio connections

       Those functions change the reference counter for connection objects previously opend via roar_connect(3),
       roar_connect_fh(3)  or  roar_simple_connect(3).   If  the  reference counter hints zero the connection is
       closed and the object is destroyed.

       The roar_disconnect(3) macro is provided to be source compatible (recompile needed) with RoarAudio 0.4 or
       older.
