The final step of _mesa_unpack_depth_span is to take the temporary
GLfloat depth values and convert them to the desired format. When
converting to GL_UNSIGNED_INTEGER with depthMax > 0xffffff, we use
double-precision math to avoid overflow and precision problems.
Or at least that's the idea. Unfortunately
GLdouble z = depthValues[i] * (GLfloat) depthMax;
actually causes single-precision multiplication, since both operands are
GLfloats. Casting depthMax to GLdouble causes the scaling to be done
with double-precision math.
Fixes a regression in oglconform's depth-stencil basic.read.ds test
since c60ac7b179, where the expected and
actual values differed slightly. For example, 0xcfa7a6 vs. 0xcfa7a4.

This forces the drivers to do at least some validation of context API

means that they don't do any post-hoc validation.

It may be possible to trim the list of extensions futher. These are
just the obvious extensions that add functionality that the core context
explicitly forbids. Apple's core-context extension list is *just* the
extensions on top of the core GL version. I'm not sure we want to go
that far, but removing some things that have been in core since 2.1 may
be okay.

After realizing that brw_finish_batch emitted some final PIPE_CONTROLs
to record occlusion queries, Chris noted that we probably hadn't
reserved enough space to actually emit them.
Reserving a full 60 bytes seems a bit harsh, since we only need that
much if occlusion queries are actually active. Plus, 28 bytes would be
sufficient for Gen7, and 24 for Gen4-5.
We could optimize this in the future, but it doesn't seem too critical.
NOTE: This is a candidate for stable release branches.

On Gen4+, brw_finish_batch() calls brw_emit_query_end(), which emits
some extra PIPE_CONTROLs to capture the current occlusion query data.
Unfortunately, it was being called *after* _intel_batchbuffer_flush
added the MI_BATCH_BUFFER_END, meaning those PIPE_CONTROLs didn't get
inside the batch.
Not only does this likely cause bogus occlusion query values, it can
also cause crashes: with the recent change to use 64-bit depth count
writes on Gen6+, we started emitting an odd-length PIPE_CONTROL, which
happened after the MI_NOOP padding. This resulted in an odd-length
batch buffer, which resulted in execbuf2 returning -EINVAL and the
application dying with an intel_do_flush_locked failure.
On older generations, finish_batch() doesn't emit any state, so this
change shouldn't have any effect.
Huge thanks to Chris Wilson for helping me figure this out.
NOTE: This is a candidate for stable release branches.
