gst/deinterlace2/: Get rid of speedy.[ch] as we don't use most of it's code anyway and it doesn't seem to be relicens...
Original commit message from CVS:

* gst/deinterlace2/tvtime/vfir.c: (deinterlace_frame_vfir):
Get rid of speedy.[ch] as we don't use most of it's code anyway
and it doesn't seem to be relicensed to LGPL. Use memcpy() instead
of the speedy memcpy everywhere instead.
* gst/deinterlace2/gstdeinterlace2.h:
Remove many unused declarations.
