The existing error result doesn't appear in the GL 2.1 or 3.2
compatibility specs, and triggers an unexpected GL error in Intel's
oglconform when it tries to reset the feedback state after usage so
that the "diff the state at error time vs. context init time" code
doesn't generate spurious diffs. The unexpected GL error then
translates into testcase failure. Brian wants the safety check on
buffer = NULL, though, so that people can't as easily set up a broken
buffer.

This code was really broken before. A lot of the error checks were

The underlying problem is that Mesa doesn't ever keep compressed paletted

The patch(based on the reading of the emulator) came from while I was
trying to fix the oglc pbo texImage.1PBODefaults fail. This case
generates a texture with the width and height equal to window's width
and height respectively, then try to texture it on the whole window.
So, it's exactly one texel for one pixel. And, the min filter and mag
filter are GL_LINEAR. It runs with swrast OK, as expected. But it failed
with i965 driver.
Well, you can't tell the difference from the screen, as the error is
quite tiny. From my digging, it seems that there are some tiny error
happened while getting tex address. This will break the one texel for
one pixel rule in this case. Thus the linear result is taken, with tiny
error.
This patch would fix all oglc pbo subcase fail with the same issue on
both ILK, SNB and IVB.
v2: comments from Ian, make the address_round filed assignment consistent.
(the sampler is alread memset to 0 by the xxx_update_samper_state

When compiling glDrawPixels, glTexImage(), etc. and we're copying
the user's image we need to be careful about GL error checking.
Previously, we were incorrectly generating GL_OUT_OF_MEMORY in
unpack_image() if width <= 0 or height <= 0 or for invalid format/type
values. We now check those arguments in unpack_image() and return NULL
if there's a bad value. The command will get compiled with the
arguments as-is and image=NULL. Later, when the command is executed the
correct errors will be generated.

If there is not enough space in pushbuffer for fence emission
(nouveau_fence_emit -> nv50_screen_fence_emit -> MARK_RING),
the pushbuffer is flushed, which through flush_notify ->
nv50_default_flush_notify -> nouveau_fence_update marks currently
emitting fence as flushed. But actual emission is done after this mark.
So later when there is a need to wait on this fence and pushbuffer
was not flushed in between, fence wait will never finish causing
application to hang.
To fix this, introduce new fence state between AVAILABLE and EMITTED,
set it before emission and handle it everywhere.
Additionally obtain fence sequence numbers after possible flush in
MARK_RING, because we want to emit fences in correct order.

intel: Recognize all depth formats in get_teximage_readbuffer.
The existing code was missing GL_DEPTH_COMPONENT32, resulting in it
wrongly returning the color buffer instead of the depth buffer.
Fixes an issue in PlaneShift 0.5.7 when casting spells. The game calls
CopyTexSubImage2D on buffers with a GL_DEPTH_COMPONENT32 internal
format, which (prior to this patch) resulted in an attempt to copy
ARGB8888 to X8_Z24.
Instead of adding the missing enumeration directly, convert the code to
use _mesa_is_depth_format() and _mesa_is_depthstencil_format() as these
should catch any newly added depth formats in the future.

As written, this test correctly raises an error for #elif being used
with an undefined macro (and not as an argument to "defined"). If the
preceding #if were '#if 1' then this diagnositc would correctly be
hidden. That allows code such as the following to not raise an error:
#ifndef MAYBE_UNDEFINED
#elif MAYBE_UNDEFINED < 5

#endif
