WIP endianness fixes

Here's some Mesa/Gallium endianness fixes I've been working on. Note that I'm
serious about 'WIP'; at the very least, this will need to be split/cleaned up,
and e.g. the util changes are just a quick'n'dirty hack which mixes driver
specific requirements into driver independent code. Also, this will probably
break colours with the r600g driver on big endian, but that should be easy to
fix by disabling its use of GPU byte swapping for textures and render targets,
and I think that's necessary anyway to work correctly in all cases possible
with OpenGL.

I'm still seeing some wrong colours e.g. in gnome-shell and assaultcube, either
I'm missing some more vital formats, or there could be similar issues with
vertex colours.
