This code was really difficult to follow, for a number of reasons:
- Queries were handled in four different ways (TIMESTAMP writes a single
value, TIME_ELAPSED writes a single pair of values, occlusion queries
write pairs of values for the start and end of each batch, and other
queries are done entirely in software. It turns out that there are
very good reasons each query is handled the way it is, but
insufficient comments explaining the rationale.
- It wasn't immediately obvious which functions were driver hooks
and which were helper functions. For example, brw_query_begin() is
a driver hook that implements glBeginQuery() for all query types, but
the similarly named brw_emit_query_begin() is a helper function that's
only relevant for occlusion queries.

having to ask how this code works and why various query types are
handled differently.

mesa: Add a new QueryCounter() hook for TIMESTAMP queries.
In OpenGL, most queries record statistics about operations performed
between a defined beginning and ending point. However, TIMESTAMP
queries are different: they immediately return a single value, and there
is no start/stop mechanism.
Previously, Mesa implemented TIMESTAMP queries by calling EndQuery
without first calling BeginQuery. Apparently this is DirectX
convention, and Gallium followed suit. I personally find the asymmetry
jarring, however---having BeginQuery and EndQuery handle a different set
of enum values looks like a bug. It's also a bit confusing to mix the
one-shot query with the start/stop model.
So, add a new QueryCounter driver hook for implementing TIMESTAMP. For
now, fall back to EndQuery to support drivers that don't do the new
mechanism.

tgsi: add texel offsets and derivatives to sampler interface
Something I never got around to implement, but this is the tgsi execution
side for implementing texel offsets (for ordinary texturing) and explicit
derivatives for sampling (though I guess the ordering of the components
for the derivs parameters is debatable).
There is certainly a runtime cost associated with this.
Unless there are different interfaces used depending on the "complexity"
of the texture instructions, this is impossible to avoid.
Offsets are always active (I think checking if they are active or not is
probably not worth it since it should mostly be an add), whereas the
sampler_control is extended for explicit derivatives.
For now softpipe (the only user of this) just drops all those new values
on the floor (which is the part I never implemented...).
Additionally this also fixes (discovered by accident) inconsistent
projective divide for the comparison coord - the code did do the
projection for shadow2d targets, but not shadow1d ones. This also
drops checking for projection modifier on array targets, since they
aren't possible in any extension I know of (hence we don't actually
know if the array layer should also be divided or not).

some wrapping modes are near impossible with fixed point (the repeat stuff)
hence we have to normalize the offsets if we can't do the wrapping in
unnormalized space (which is a division which is slow but should still be
much better than the alternative, which would be integer modulo for wrapping
which is just unusable). This should still give accurate results in all
