But this won't work at this point, since _mesa_is_gles3 requires
ctx->Version to be set and that will not happen until late

We can't just move the call to _mesa_compute_version before
_mesa_initialize_context since it needs that available extensions
have been computed, which again requires other things to be

GLES2, which should work for most implementations, and expect

i965: Perform program state upload outside of atom handling

Across the board of the various generations, the intial few atoms in
all of the atom lists are basically the same, (performing uploads for
the various programs). The only difference is that prior to gen6
there's an ff_gs upload in place of the later gs upload.

In this commit, instead of using the atom lists for this program state
upload, we add a new function brw_upload_programs that calls into the
per-stage upload functions which in turn check dirty bits and return
immediately if nothing needs to be done.

This commit is intended to have no functional change. The motivation
is that future code, (such as the shader cache), wants to have a
single function within which to perform various operations before and
after program upload, (with some local variables holding state across
the upload).

It may be worth looking at whether some of the other functionality
currently handled via atoms might also be more cleanly handled in a
similar fashion.

egl, wayland: RGB565 format support on Back-buffer

In current code, color format is always hardcoded to
__DRI_IMAGE_FORMAT_ARGB8888 when buffer or DRI image is
allocated in function calls, get_back_bo and dri2_get_buffers,
regardless of current target's color format. This problem
may leads to incorrect render pitch calculation, which
eventually ends up with wrong offset of pixels in
the frame buffer when the image is in different color format
from dri surf's, especially with different bpp. (e.g. RGB565-16bpp)

Attached code patch simply adds RGB565 and XRGB8888 cases to two
functions noted above to resolve the issue.

v2: added a case of XRGB8888, format and bpp selection is done
    via switch-case (not "if-else" anymore)

ra: Disable round-robin strategy for optimistically colorable nodes.

The round-robin allocation strategy is expected to decrease the amount
of false dependencies created by the register allocator and give the
post-RA scheduling pass more freedom to move instructions around.  On
the other hand it has the disadvantage of increasing fragmentation and
decreasing the number of equally-colored nearby nodes, what increases
the likelihood of failure in presence of optimistically colorable
nodes.

This patch disables the round-robin strategy for optimistically
colorable nodes.  These typically arise in situations of high register
pressure or for registers with large live intervals, in both cases the
task of the instruction scheduler shouldn't be constrained excessively
by the dense packing of those nodes, and a spill (or on Intel hardware
a fall-back to SIMD8 mode) is invariably worse than a slightly less
optimal scheduling.
