i965/screen: Add basic support for rendering 10 bpc/depth 30 framebuffers. (v3)
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. 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. v3: Use num_formats = ARRAY_SIZE(formats) - 2 as suggested by Tapani, to only exclude the last 2 Android formats, add Tapani's r-b.
