foreach_iter and exec_list_iterators have been deprecated for some time now;
we just hadn't ever bothered to convert code to the newer foreach_list
and foreach_list_safe macros.
In these cases, we aren't editing the list, so we can use foreach_list
rather than foreach_list_safe.

Prior to this patch, if we ran out of aperture space during
brw_try_draw_prims(), we would rewind the batch buffer pointer
(potentially throwing some state that may have been emitted by
brw_upload_state()), flush the batch, and then try again. However, we
wouldn't reset the dirty bits to the state they had before the call to
brw_upload_state(). As a result, when we tried again, there was a
danger that we wouldn't re-emit all the necessary state. (Note: prior
to the introduction of hardware contexts, this wasn't a problem
because flushing the batch forced all state to be re-emitted).
This patch fixes the problem by leaving the dirty bits set at the end
of brw_upload_state(); we only clear them after we have determined
that we don't need to rewind the batch buffer.

Previously, Mesa enforced the following rule (from
ARB_geometry_shader4's list of criteria for framebuffer completeness):
* If any framebuffer attachment is layered, all attachments must have
the same layer count. For three-dimensional textures, the layer count
is the depth of the attached volume. For cube map textures, the layer
count is always six. For one- and two-dimensional array textures, the
layer count is simply the number of layers in the array texture.
{ FRAMEBUFFER_INCOMPLETE_LAYER_COUNT_ARB }
However, when ARB_geometry_shader4 was adopted into GL 3.2, this rule
was dropped; GL 3.2 permits different attachments to have different
layer counts. This patch brings Mesa in line with GL 3.2.
In order to ensure that layered clears properly clear all layers, we
now have to keep track of the maximum number of layers in a layered
framebuffer.
Fixes the following piglit tests in spec/!OpenGL 3.2/layered-rendering:
- clear-color-all-types 1d_array mipmapped
- clear-color-all-types 1d_array single_level
- clear-color-mismatched-layer-count
- framebuffer-layer-count-mismatch

Commit 1a92881 added extra flushes to fix a HiZ hang in
WebGL Google Maps. With the extra flushes emitted by the previous two
patches, the flushes added by 1a92881 are redundant.
Tested with the same criteria as in 1a92881: by zooming in and out
continuously for 2 hours on Sandybridge Chrome OS (codename
Stumpy) without a hang.

Unconditionally set brw->need_workaround_flush at the top of gen6 blorp
state emission.
The art of emitting workaround flushes on Sandybridge is mysterious and
not fully understood. Ken and I believe that
intel_emit_post_sync_nonzero_flush() may be required when switching from
regular drawing to blorp. This is an extra safety measure to prevent
undiscovered difficult-to-diagnose gpu hangs.
I verified that on ChromeOS, pre-patch, need_workaround_flush was not
set at the top of blorp, as Paul expected. To verify, I inserted the
following debug code at the top of gen6_blorp_exec(), restarted the ui,
and inspected the logs in /var/log/ui. The abort gets triggered so early
that the browser never appears on the display.
static void
gen6_blorp_exec(...)
{
if (!brw->need_workaround_flush) {
fprintf(stderr, "chadv: %s:%d\n", __FILE__, __LINE__);
abort();
}

This patch makes the workaround code in gen6 blorp follow the pattern
established in the regular draw path. It shouldn't result in any
behavioral change.
On gen6, there are two places where we emit 3D_CMD_PRIM: brw_emit_prim()
and gen6_blorp_emit_primitive(). brw_emit_prim() sets
need_workaround_flush immediately after emitting the primitive, but
blorp does not. Blorp sets need_workaround_flush at the bottom of
brw_blorp_exec().
This patch moves the need_workaround_flush from brw_blorp_exec() to
gen6_blorp_emit_primitive(). There is no need to set
need_workaround_flush in gen7_blorp_emit_primitive() because the
workaround applies only to gen6.

We definitely want to fall through to the unsynchronized map case, instead
of wasting bandwidth on a copy. Prevents a -43.2407% +/- 1.06113% (n=49)
performance regression on aa10perf when teaching glamor to provide the
GL_INVALIDATE_RANGE_BIT information.
This is a performance fix, which I usually wouldn't cherry-pick to stable.
But this was really was just a bug in the code, its presence would
discourage developers from giving us the best information they can, and I
think we've got fairly high confidence in the unsynchronized map path
already.

While incorrect, it probably wouldn't affect anyone ever: You'd have to do
an appropriately-formatted readpixels into a PBO, then overwrite the tail
end of the updated area of the PBO with glBufferSubData(), and you
wouldn't get appropriate synchronization.

The earlier assert made sure that our math didn't exceed our bounds, but
this makes sure that we don't overflow from the high bits X into the low
bits of Y. We've already put checks in intel_miptree_blit(), but I've
wanted to expand the type in our protoype from short to uint32_t, and we
could get in trouble with intel_emit_linear_blit() if we did.

The hardware is broken with nonzero texel offsets and unnormalized
coordinates; instead of doing correct offsetting, we get garbage.
This just extends the existing workaround for ir_txf and
ir_tg4+gsampler2DRect to also consider ir_tex+gsampler2DRect.
Fixes broken rendering in 'tesseract' when 'mesa_texrectoffset_bug' is
not enabled; also fixes the new piglit test
'tests/spec/glsl-1.30/execution/fs-textureOffset-Rect'.
Has been broken ~forever; suggesting including this in only 10.0 because
the lowering pass doesn't exist in 9.2 or earlier so would require quite
a different patch.

This reduces confusion since gl_shader::Type is sometimes
GL_SHADER_PROGRAM_MESA but is more frequently
GL_SHADER_{VERTEX,GEOMETRY,FRAGMENT}. It also has the advantage that
when switching on gl_shader::Stage, the compiler will alert if one of
the possible enum types is unhandled. Finally, many functions in
src/glsl (especially those dealing with linking) already use
gl_shader_stage to represent pipeline stages; using gl_shader::Stage
in those functions avoids the need for a conversion.
Note: in the process I changed _mesa_write_shader_to_file() so that if
it encounters an unexpected shader stage, it will use a file suffix of
"????" rather than "geom".

Previously, we had an enum called gl_shader_type which represented
pipeline stages in the order they occur in the pipeline
(i.e. MESA_SHADER_VERTEX=0, MESA_SHADER_GEOMETRY=1, etc), and several
inconsistently named functions for converting between it and other
representations:
- _mesa_shader_type_to_string: gl_shader_type -> string
- _mesa_shader_type_to_index: GLenum (GL_*_SHADER) -> gl_shader_type
- _mesa_program_target_to_index: GLenum (GL_*_PROGRAM) -> gl_shader_type
- _mesa_shader_enum_to_string: GLenum (GL_*_{SHADER,PROGRAM}) -> string
This patch tries to clean things up so that we use more consistent
terminology: the enum is now called gl_shader_stage (to emphasize that
it is in the order of pipeline stages), and the conversion functions are:
- _mesa_shader_stage_to_string: gl_shader_stage -> string
- _mesa_shader_enum_to_shader_stage: GLenum (GL_*_SHADER) -> gl_shader_stage
- _mesa_program_enum_to_shader_stage: GLenum (GL_*_PROGRAM) -> gl_shader_stage
- _mesa_progshader_enum_to_string: GLenum (GL_*_{SHADER,PROGRAM}) -> string
In addition, MESA_SHADER_TYPES has been renamed to MESA_SHADER_STAGES,
for consistency with the new name for the enum.

* The Haiku renderers need to link to libGL to function properly
in all usage contexts. As mesa drivers build before gallium
targets, we couldn't properly link the mesa swrast driver to
the gallium libGL target for Haiku.
* This is likely better as it mimics how glx is laid out ensuring
the Haiku libGL is better understood.
* All renderers properly link in libGL now.

MESA_FORMAT_XRGB8888 is equivalent to MESA_FORMAT_ARGB8888 in terms
of storage on the device, so okay to use this optimized copy routine.
This series builds on work from Frank Henigman to optimize the
process of uploading a texture to the GPU. This series adds support for
MESA_XRGB_8888 and full miptrees where were found to be common activities
in the Smokin' Guns game. The issue was found while profiling the app
but that part is not benchmarked. Smokin-Guns uses mipmap textures with
an internal format of GL_RGB (MESA_XRGB_8888 in the driver).
These changes need a performance tool to run against to show how they
improve execution performance for specific texture formats. Using this
benchmark I've measured the following improvement on my Ivybridge

Previously, _mesa_glsl_shader_target_name() had an overload for GLenum
and an overload for the gl_shader_type enum, each of which behaved
differently. However, since GLenum is a synonym for unsigned int, and
unsigned ints are often used in place of gl_shader_type (e.g. in loop
indices), there was a big risk of calling the wrong overload by
mistake. This patch gives the two overloads different names so that
it's always clear which one we mean to call.
