orphaning xine-lib, EOL'ing phonon-backend-xine

[Rex Dieter]

The labor of love that was maintaining xine-lib has passed, as it will no 
longer be a dependency in f16's kde stack in any form.  As such, I'm 
orphaning it.  Kevin Kofler has offered to take ownership, though I'd 
venture he'd welcome any comaintainer assistance offered.

In a similar vein, phonon-backend-xine has officially been deprecated and is 
no longer supported.  We'll be EOL'ing this one soon.
