sys/glsink/: Remove code that handles non-texture buffers. Add a

Original commit message from CVS:
* sys/glsink/BUGS:
* sys/glsink/Makefile.am:
* sys/glsink/gstglbuffer.c:
* sys/glsink/gstglbuffer.h:
* sys/glsink/gstglconvert.c:
* sys/glsink/gstgldisplay.c:
* sys/glsink/gstglfilter.c:
* sys/glsink/gstglfilter.h:
* sys/glsink/gstglfilterexample.c:
* sys/glsink/gstgltestsrc.c:
* sys/glsink/gstglupload.c:
* sys/glsink/gstopengl.c:
Remove code that handles non-texture buffers.  Add a
GstGLBufferFormat type that corresponds to how to use the
texture, not the original video format.  Convert gstflfilter.c
into a base class, add glfilterexample and glconvert elements.
* sys/glsink/color_matrix.c:
Minor ramblings about color conversion matrices.
