Subject:  * avahi-client/    - Create a new function avahi_dbus_bus_get which
 acts like      dbus_bus_get but instead gets a private connection, this
 solves      the bug where you can't have more than one AvahiClient at once   
   because each successive AvahiClient stepped on the DBusWatch      handling
 of the previous due to libdbus liking to recycle      its connections.

     Introduced a new configure option --with-dbus-system-address=
     if you set this, you likely want it set to
     unix:path=/some/socket/here

     The default is /var/run/dbus/system_socket_address, because
     this path is hard coded into D-BUS itself, and the
     DBUS_SYSTEM_BUS_ADDRESS environment variable is now supported
     to change this at runtime which is inline with libdbus.
