anv: use cElementTree in anv_entrypoints_gen.py

It's written in C rather than pure python and is strictly faster, the

anv: don't use Element.get in anv_entrypoints_gen.py

This has the potential to mask errors, since Element.get works like
dict.get, returning None if the element isn't found. I think the reason
that Element.get was used is that vulkan has one extension that isn't
really an extension, and thus is missing the 'protect' field.

This patch changes the behavior slightly by replacing get with explicit
lookup in the Element.attrib dictionary, and using xpath to only iterate
over extensions with a "protect" attribute.

prevents bugs where a symbol (generally unicode like © [copyright]) is

One thing to note is the use of '{{' and '}}' in the C template. This is

isl: Refactor row pitch calculation (v2)

The calculations of row_pitch, the row pitch's alignment, surface size,
and base_alignment were mixed together. This patch moves the calculation
of row_pitch and its alignment to occur before the calculation of
surface_size and base_alignment.

This simplifies a follow-on patch that adds a new member, 'row_pitch',
to struct isl_surf_init_info.

i965/dri: Handle Y-tiled modifier

This patch begins introducing how we'll actually handle the potentially
many modifiers coming in from the API, how we'll store them, and the
structure in the code to support it.

Prior to this patch, the Y-tiled modifier would be entirely ignored. It
shouldn't actually be used until this point because we've not bumped the
DRIimage extension version (which is a requirement to use modifiers).

Measuring later in the series with kmscube:
Linear:

Y-tiled:

i965/dri: Handle the linear fb modifier

At image creation create a path for dealing with the linear modifier.
This works exactly like the old usage flags where __DRI_IMAGE_USE_LINEAR
was specified.

During development of this patch series, it was decided that a lack of
modifier was an insufficient way to express the required modifiers. As a
result, 0 was repurposed to mean a modifier for a LINEAR layout.

NOTE: This patch was added for v3 of the patch series.

v2: Rework the algorithm for modifier selection to go from a bitmask
based selection to this priority value.

v3: Make DRM_FORMAT_MOD_INVALID allowed at selection as a way of

i965/dri: Enable modifier queries

New to the patch series after reordering things for landing smaller
chunks.

This will essentially enable modifiers from clients that were just
enabled in previous patches. A client could use the modifiers by
setting all of them at create, but had no way to actually query them
after creating the surface (ie. stupid clients could be broken before
this patch, but in more ways than this).

Obviously, there are no modifiers being actually stored yet - so this
patch shouldn't do anything other than allow the API to get back 0 (or
the LINEAR modifier).

i965: Use aubinator/genxml for INTEL_DEBUG=bat state decoding.

This deletes all of our handwritten code in favor of autogenerated

code isn't entirely accurate - we updated some things for new
generations, but not everything.

Aubinator has one annoying limitation: it has no idea how many entries
to print when encountering e.g. 3DSTATE_BINDING_TABLE_POINTERS_VS.  It
picks an arbitrary number, which may skip decoding valid data, and may
print extra garbage entries.

We do a better job here by making brw_state_batch track the size of the
data stored at a particular batchbuffer offset.  Then, we can divide by
the structure size to obtain the exact number of entries.
