Fixed FTBFS with xine 1.2.10. The use of the xine scope plugin is currently

disabled when xine >= 1.2.10 is detected.
This resolves bug 3065 and 3066.

Additional info:
The xine scope plugin is statically linked and therefore written by
accessing internal xine data that are no longer publicly available from
xine 1.2.10.
To add back the scope plugin functionality, the plugin will have to be
converted into a dynamically linked one and further work done to fix the
logic of the plugin itself.
