i965: Stop including brw_vs.h from brw_vec4.h.

This is backwards from what we are going to want in the long term, which is:

- brw_vec4.h declares general-purpose vec4 infrastructure needed by
  both VS and GS
- brw_vs.h includes brw_vec4.h and adds VS-specific parts.
- brw_gs.h includes brw_vec4.h and adds GS-specific parts.

Note that at the moment brw_vec.h contains a fair amount of
VS-specific declarations--I plan to address that in a later patch.

mesa: Specify a better GL_MAX_SERVER_WAIT_TIMEOUT limit.

The previous value of (GLuint64) ~0 has some problems:

GL_MAX_SERVER_WAIT_TIMEOUT is supposed to be a GLuint64 value, but has
to be queried via GetInteger64v(), which returns a GLint64.  This means
that some applications are likely to treat it as a signed integer, where
~0 means -1.  Negative values are nonsensical and problematic.

When interpreted correctly, ~0 translates to about 0.58 million years,
which seems rather excessive.

This patch changes it to 0x1fff7fffffff, which is about 1.11 years.
This is still plenty long, and is the same as both an int64 and uint64.
Applications that accidentally store it in a 32-bit int/unsigned also

Chad Versace [Wed, 21 Aug 2013 00:36:24 +0000 (17:36 -0700)]
i965: Fix misapplication of gles3 srgb workaround

Fixes inconsistent failure of gles2conform/GL2Tests/glUniform/glUniform.test
under gnome-shell. What follows is a description of the bug and its fix.

When intel_update_renderbuffers() allocates a miptree for a winsys
renderbuffer, it propagates the renderbuffer's format to become also the
miptree's format.

If the winsys color buffer format is SARGB, then, in the first call to
eglMakeCurrent, intel_gles3_srgb_workaround() changes the renderbuffer's
format to ARGB. That is, it changes the format from sRGB to non-sRGB.
However, it changes the renderbuffer's format *after*
intel_update_renderbuffers() has allocated the renderbuffer's miptree.
Therefore, when eglMakeCurrent returns, the miptree format (SARGB)
differs from the renderbuffer format (ARGB).

If the X server reallocates the color buffer,
intel_update_renderbuffers() will create a new miptree for the
renderbuffer. The new miptree's format (ARGB) will differ from old
miptree's format (SARGB). This mismatch between old and new miptrees
causes bugs.

Fix the bug by moving intel_gles3_srgb_workaround() to occur *before*
intel_update_renderbuffers().

i965/fs: Separate the updating of liveout/livein.

To compute the actual liveout/livein data flow values, we start with
some initial values and apply a fixed-point algorithm until they settle.

Previously, we iterated through all blocks, updating both liveout and
livein together in one pass.  This is awkward, since computing livein
for a block requires knowing liveout for all parent blocks.  Not all
of those parent blocks may have been processed yet.

This patch separates the two.  First, we update liveout for all blocks.
At iteration N of the fixed-point algorithm, this uses livein values
from iteration N-1.  Secondly, we update livein for all blocks.  At
step N, this uses the liveout information we just computed (in step N).

This ensures each computation has a consistent picture of the data,
rather than seeing an random mix of data from steps N-1 and N depending
