hardware can't do some formats natively.  The alpha-only, luminance,
and intensity formats are usually the most problematic.  Some sized
formats can also be problematic.  This patch provides fall-back
formats for those that are not natively supported.

At some point it would be interesting to try providing
device-independent conversions using EXT_texture_swizzle.  The drivers
that support EXT_texture_swizzle could, for example, see
GL_LUMINANCE16_SNORM as MESA_FORMAT_SIGNED_R16 with a { r, r, r, 1 }
swizzle.  Care would need to be taken to prevent issues with using

intel: Don't leak the tex object miptree when replacing it

Eventually the miptree refcounting interface should be cleaned up.
The assymmetry dramatically increases the probability of bugs like
this.  It should be made to like like libdrm refcounting or the
refcounting style used in other parts of Mesa.
