Expose formats which are supported at least back to Gen 5 Ironlake,
possibly further. Allow creation of 10 bpc winsys buffers for drawables.
glxinfo now lists new RGBA 10 10 10 2/0 formats.
Works correctly under DRI2 without compositing.
v2: Move the BGRA/BGRX1010102 formats before the RGBA/RGBX8888
32 bit formats, as the code comments require. Thanks Emil!
Update num_formats from 3 to 5, to keep the special Android
handling intact.
