[PATCH]: adapt to new DBusWatch api

[Kel Modderman]

Hi,

Concerning the following compile warnings:

ctrl_iface_dbus.c: In function 'connection_setup_add_watch':
ctrl_iface_dbus.c:86: warning: 'dbus_watch_get_fd' is deprecated (declared 
at /usr/include/dbus-1.0/dbus/dbus-connection.h:357)
ctrl_iface_dbus.c: In function 'connection_setup_remove_watch':
ctrl_iface_dbus.c:111: warning: 'dbus_watch_get_fd' is deprecated (declared 
at /usr/include/dbus-1.0/dbus/dbus-connection.h:357)

The DBusWatch api has tagged dbus_watch_get_fd as deprecated in favour of
dbus_watch_get_unix_fd [0].

Attached patch directly changes to this api, as I cannot think of sane way to
add compile time test of DBUS_VERSION_* or the like.
