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.
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.

Could previously emit opcodes with label arguments, but was no way to
patch them with the actual destinations of those labels.
Adds two functions:
ureg_get_instruction_number - to get the id of the next instruction
to be emitted
ureg_fixup_label - to patch an emitted label to point to a given
instruction number.
Need some more complex examples than u_simple_shader, so far this has
only been compile-tested.
