Previously, when the environment variable INTEL_DEBUG=aub was set,
mesa would simply instruct DRM to start dumping data to an .aub file,
but we would not provide DRM with any information about the format of
the data in various buffers. As a result, a lot of the data in the
generate .aub file would be unannotated, making further data analysis
difficult.
This patch causes the entire contents of each batch buffer to be
annotated using the data in brw->state_batch_list (which was
previously used only to annotate the output of INTEL_DEBUG=bat). This
includes data that was allocated by brw_state_batch, such as binding
tables, surface and sampler states, depth/stencil state, and so on.
The new annotation mechanism requires DRM version 2.4.34.

When we are generating an AUB dump, we make a final call to
aub_dump_bmp() as the context is being destroyed, to ensure that any
rendering performed before the application exits can be seen during a
simulation run. However, we were doing this before flushing the batch
buffer; as a result simulation runs would not always see the effect of
all rendering commands.
This patch flushes the batch buffer just before making the final call
to aub_dump_bmp(), to ensure that all rendering is properly captured
in the final bitmap.
This is a long standing problem, that recently surfaced with the change
to enable perspective correct color interpolation.
A fix for all possible formats is left to the future.

This patch removes two Clang warnings in GLU:
The first one seems to be an actual bug in mapdesc.cc: Clang complains
that sizeof(dest) will return the size of REAL*[MAXCOORDS], instead of
the intended REAL[MAXCOORDS][MAXCOORDS]. The second one is just
cosmetic because Clang doesn't like extra parentheses.

Fixes another case of sampler views being created by one context,
shared by another, then deleted by the first, leaving a dangling

Use it where performance matters more and the exact method of float->int
conversion/rounding isn't terribly important. There should no net change
here since F_TO_I() is the new name of the old IROUND() function.
Reviewed-by: José Fonseca <jfonseca@vmware.com>
The different implementations of IROUND() behaved differently and in
the case of fistp, depended on the current x86 FPU rounding mode.
This caused some tests like piglit roundmode-pixelstore and
roundmode-getintegerv to fail on 32-bit x86 but pass on 64-bit x86.
Now IROUND() always rounds to the nearest integer (away from zero).
The new F_TO_I function converts a float to an int by whatever means
is fastest. We'll use this where we're more concerned with performance
and not too worried to how the conversion is done.

The IROUND converted all arguments to 0 or 1. That's not what we wanted.

For zero-stride vertex arrays, the svga driver copies the value into
the constant value and uses that value in the shader. The recent
gallium-userbuf changes caused a regression in this. An example
symptom was per-primitive glColor3f() calls getting ignored.
Where we copied the vertex value from the vertex buffer to the
constant buffer we neglected to take into account the
pipe_vertex_buffer::buffer_offset field. Adding that value to the
source offset fixes the problem. Actually, it looks like we should
have been doing this all along, but it never was an issue before for
some reason.
If the MESA_GLSL env var contains "errors", GLSL compilation and
link errors will be reported to stderr.
