t_dd_dmatmp: Make "count" actually be the count

The value passed in count previously was "vertex after the last vertex
to be processed."  Calling that "count" was misleading and kind of mean.
Looking at the code, many functions immediately do "count-start" to get
back the true count.  That's just silly.

If it is better for the loops to be 'for (j = start; j < (start +
count); j++)', GCC will do that transformation.

NOTE: There is some strange formatting left by this patch.  That was
done to make it more obvious that the before and after code is
equivalent.  These will be fixed in the next patch.

No piglit regressions on i915 (G33) or radeon (Radeon 7500).

v2: Fix a remaining (count-start) in render_quad_strip_verts.
