We used to overallocate the output buffer sometimes running out
of memory with applications rendering large geometries. The actual
maximum number of vertices out is simply the maximum number of
primitives in (number of gs invocations) multiplied by the maximum
number of output vertices per gs input primitive (i.e. gs invocation).

It is quite hard to meet the dependency of the libxml2 python bindings
outside Linux, and in particularly on MacOSX; whereas ElementTree is
part of Python's standard library. ElementTree is more limited than
libxml2: no DTD verification, defaults from DTD, or XInclude support,
but none of these limitations is serious enough to justify using
libxml2.
In fact, it was easier to refactor the code to use ElementTree than to
try to get libxml2 python bindings.
In the process, gl_item_factory class was refactored so that there is
one method for each kind of object to be created, as it simplifies
things substantially.
I confirmed that precisely the same output is generated for GL/GLX/GLES.

This patch introduces two pre-canned MOCS values: BDW_MOCS_WB
(write-back, all caches) and BDW_MOCS_WT (write-through, all caches).
We use write-through caching for render targets, and write-back for
all other data. (At least on Haswell, I believe write-back LLC/eLLC
didn't work for scan-out buffers, while write-through did.)
No performance analysis has been done on the impact of this patch.

Core profile requires a non-default VAO to be bound. Currently, calls
to glVertexAttribPointer raise INVALID_OPERATION unless a VAO is bound,
and we never actually get any vertex data set. Trying to draw without
any vertex data can only cause problems. In i965, it causes a crash.

Implementation note:
I don't use context for ralloc (don't know how).
The check on PROGRAM_SEPARABLE flags is also done when the pipeline
isn't bound. It doesn't make any sense in a DSA style API.
Maybe we could replace _mesa_validate_program by
_mesa_validate_program_pipeline. For example we could recreate a dummy
pipeline object. However the new function checks also the
TEXTURE_IMAGE_UNIT number not sure of the impact.

This is much like _mesa_sampler_uniforms_are_valid, but it operates
across an entire pipeline object.
This function differs from _mesa_sampler_uniforms_are_valid in that it

some temporary buffer.

The SIMD16 replicated FB write message only works if we don't need the
color calculator to mask our framebuffer writes. Previously, we bailed
on it if color_mask wasn't <true, true, true, true>. However, this was
needlessly strict for formats with fewer than four components - only the
components that actually exist matter.
WebGL Aquarium attempts to clear a BGRX texture with the ColorMask set
to <true, true, true, false>. This will work perfectly fine with the
replicated data message; we just bailed unnecessarily.
Improves performance of WebGL Aquarium on Iris Pro (at 1920x1080) by
abound 50%, and Bay Trail (at 1366x768) by over 70% (using Chrome 24).
