Enables ARB_depth_buffer_float. There is no sampling support for
interleaved Z32F_S8, so we store the two textures separately, one as
Z32F, the other as S8. As a result, we need a lot of additional logic
for restores and transfers.

copy drivers from the stencil_texturing list,
softpipe is definitely broken for stencil texturing
since it uses float, but I'll look at that later.

Switch between the two clip space definitions already available
in hardware. Update winding order dependent state according
to the clip control state.
This change did not introduce new piglit quick.test regressions on
an Ivybridge Mobile and a GM45 Express chipset.
Also it enables and passes the clip-control and clip-control-depth-precision
tests on these two chipsets.

The hardware only supports 4 MRTs. It should be possible to emulate
support for 8, but doesn't seem worth the trouble.

At the moment to get an EGL image to a dma-buf file descriptor,
you have to use EGL_MESA_drm_image, and then use libdrm to
convert this to a file descriptor.
This extension just provides an API modelled on EGL_MESA_drm_image,
to return a dma-buf file descriptor.
v2: update spec for new API proposal
add internal queries to get the fourcc back from intel driver.
v2.1: add gallium pieces.
v2.2: add offsets to spec and API, rename fd->fds, stride->strides
in API. rewrite spec a bit more, add some q/a
v2.3:
add modifiers to query interface and 64-bit type for that (Daniel Stone)
specifiy what happens to num fds vs num planes differences. (Chad Versace)
v2.4:
fix grammar (Daniel Stone)

Just announce support for 4 components.
While here also increase the max/min texel offsets (the limit is completely
artificial, was chosen because that's what other hardware did, however there's
other drivers using larger limits).
Over a thousand little piglits skip->pass.
