don't convert planar yuv to packed for r300

uses 3 textures for planar yuv and does yuv->rgb conversion in the shader.
small performance advantage, but manual texture cache setting is necessary
otherwise it may be measurably slower (but probably not relevant) in some
cases.
Unlike some other drivers, using MADs instead of DP3s, since this requires
less instructions due to no MOVs are required, the end result is the same
though the constants need to be different.
Use of this is user settable for now (XV_HWPLANAR attrib).
