Patch adds prediction functionthat tries to predict emit size to the smallest
possible values that is quarenteed to be higher than worst case scenario in
rendering pipeline.
State emit size prediction code is in place but fix for emit sizes is included
in next patch.

This fixes bug that xdemos/manywin would segfault if it was run with command
./manywin 2. Demo is tring to call glXSwapBuffers while another context was
bind using glXMakeCurrent.
Fix is simple makes drawable and readable persistent untill they change or
context is destroyed.
I found a logic error when same dri context is used for multiple drawables
which caused readable and drawable to fall out of sync in special case. Fix
is simple just updating drawables more often than in original patch.

The real difference is that the driver suffix is now appended. This
also fixes an annoying bug that EGL_DRIVER could not specify the path to
a driver because a suffix was always appended.

libX11 is used to determine the screen number, which is in turned used
to determine the DRI driver. However, the sysfs interface for
determining the DRI driver is gone, and no working driver depends on
this mechanism.
Display string parsing is moved to a new function,
_eglSplitDisplayString.

The commit "ARP prog parser: Implement the spec, not what makes sense"
broke the parsing of scalar constants. This commit reverts that part
of that commit. Now vp_swizzle.c passes.
Let eg. sp_get_samples_rect be hooked directly in as the tgsi sampler
routine.
Add a field to determine whether this is a vertex or fragment sampling
call, and massage parameters to match the tgsi call.
Fixes two issues - firstly for mipmap levels with one or more
dimensions smaller than tilesize, the code was sampling off the edge
of the texture (but still within the tile).
Secondly, in the linear_mipmap_linear case, both the default code and
new fastpath were incorrect. This change fixes the fastpath and adds
a comment to the default path, which still needs to be fixed.
Basically the issue is that the coordinates in the smaller texture
level are/were being computed by just dividing thecoordinates from the
larger texture level by two, as in:
x0[j] /= 2;
y0[j] /= 2;
x1[j] /= 2;
y1[j] /= 2;
The issues with this are signficant. Initially x1 is most often equal
to x0+1, but after this, it will likely be equal to x0, so we will not
actually be performing the linear blend within the smaller mipmap.
The fastpath code avoided this (recalculated x1), but was still using
the weighting factors from the larger mipmap level (xw, yw), which
were incorrect.
Change the fastpath code to do two full, independent linear samples of
the two mipmap levels before blending. The default code needs to do
the same thing.
SOA dependencies can happen when a register is used both as a source and
destination and the source is swizzled. For example:
MOV T, T.yxwz; would expand into:
MOV t0, t1;
MOV t1, t0;
MOV t2, t3;
MOV t3, t2;
The second instruction will produce the wrong result since we wrote to t0
in the first instruction. We need to use an intermediate temporary to fix
this.
This will take more work to fix for all TGSI instructions. This seems to
happen with MOV instructions more than anything else so fix that case now
and warn on others.
Fixes piglit glsl-vs-loop test (when not using SSE). See bug 23317.

linear-mip-linear-repeat-POT sampling faspath, provides a very nice
speedup to apps that do this common type of texturing.
Test case: demos/terrain, turn fog off, turn texturing on.
Without patch: 12 fps
With patch: 20 fps.
