util: Fix 24 to 32 bit expansion binary arithmetic expression.
When approaching y = x * 0xffffffff / 0xffffff with bit arithmetic, the
8 least significant bits of y should come from the
8 most significant bits of x.
draw: reset extra_vp_outputs.slot to zero in widepoint_flush()
Fixes a crash when clearing the window with a quad after drawing large
points. We were asking the draw module how many vertex shader outputs
there were and got 3 instead of 2. This led to creating vertices with
too many attributes and trying to read invalid memory.
We reset extra_vp_outputs.slot to zero in the aaline/aapoint stage's
flush functions already.
This omission was just an oversight in the wide_point stage.
gallium/tgsi: hack around linker/archiver breakage
Add a dummy function which exists only so that tgsi_text_translate()
doesn't get magic-ed out of the libtgsi.a archive by the build system.
Don't remove unless you know this has been fixed - check on
mingw/scons builds as well.

tgsi: added tgsi_check_soa_dependencies() and related debug code (disabled)
The TGSI interpeter operates in SOA style. We need to check for data
dependencies in instructions which read from and write to the same register.
For now just adding some debug code to detect that condition. Actual fixes
to follow.
pipebuffer: don't fail when validating mapped buffers
This can be almost impossible to avoid - hopefully we won't encounter
a situation where this is a true requirement. Would probably require
drivers to flush between hardware and software vertex processing.
