The LOD is computed from texcoord partial derivatives and used to
select a mipmap level. Still some bugs in texel fetching. Lots of
rough edges and unfinished parts but the basics are in place.
Lots of changes to the lp_bld_arit.c code to support non-vector/scalar
datatypes.
Several software rasterizers can make use of this winsys, but there
isn't any reason why the winsys itself should know about them.
This change moves that information into the libgl-xlib target.
Need to fix up other targets making use of this winsys.
Don't make the shared software winsys rely on internal knowledge about
the cell driver's texture twiddling.
This is just a sketch and hasn't even been compile tested.
While this c99 feature should work with most compilers, valgrind doesn't
really like it, and this only really saves some memory, we don't do this
in similar occasions (like the blend state) neither.

gallium: remove p_screen::surface_buffer_create
This isn't very useful without texture_blanket(), which has also been
removed.
Note that this function hasn't been removed from the old pipe_winsys
(u_simple_screen) still used internally by some drivers (eg softpipe).

gallium: remove texture blanket call
No longer needed, except for nouveau and egl/xll/native_ximage.c.
Fix for nouveau is to keep the call, but move it to an internal
function within nouveau.
Fix for that egl/x11 relies on gallium-sw-api branch or its successor.

drm_api: wrap comment
Change the texture data_ptr from just a single image pointer to an
array of image pointers, indexed by mipmap level.
We'll use this for mipmap filtering.
For now, the mipmap level is hard-coded to zero.
