Adds 0-3 textureGather component selection and non-constant offsets
Caveat: 0 and 1 texture swizzles only work if textureGather component
select is 3 or a component that does not exist in the sampler texture
format. This is a hardware limitation, any other value returns
128/255=0.501961 for both 0 and 1.
Passes all textureGather piglit tests on radeon 6670, except for those
using 0/1 texture swizzles due to aforementioned reason.

Add a new winsys and target that can be used with a dri2 state tracker
and loader instead of drisw. This allows to use gbm as a dri2/image
loader and avoid the extra copy from the backbuffer to the shadow
frontbuffer.
The new driver is called "kms_swrast", and is loaded by gbm as a
fallback, because it is only useful with the gbm platform (as no buffer
sharing is possible)
To force select the driver set the environment variable

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.

It turns out we can allow COHERENT storage/mappings all the time,
regardless of LLC vs non-LLC. It just means never using temporary
mappings to avoid GPU stalls, and on non-LLC we have to use the GTT intead
of CPU mappings. If we were to use CPU maps on non-LLC (which might be
useful if apps end up using buffer_storage on PBO reads, to avoid WC read
slowness), those would be PERSISTENT but not COHERENT, but doing that
would require us driving the clflushes from userspace somehow.

This extension provides a way for an application to render to multiple
surfaces with different buffer formats without having to use multiple
contexts. An EGLContext can be created without an EGLConfig by passing
EGL_NO_CONFIG_MESA. In that case there are no restrictions on the surfaces
that can be used with the context apart from that they must be using the same
EGLDisplay.
_mesa_initialze_context can now take a NULL gl_config which will mark the
context as ‘configless’. It will memset the visual to zero in that case.
Previously the i965 and i915 drivers were explicitly creating a zeroed visual
whenever 0 is passed for the EGLConfig. Mesa needs to be aware that the
context is configless because it affects the initial value to use for
glDrawBuffer. The first time the context is bound it will set the initial
value for configless contexts depending on whether the framebuffer used is
double-buffered.

On earlier hardware, we had to implement math in the shader to translate
Y-tiled or untiled coordinates to W-tiled coordinates (which is what
BLORP does today in order to texture from stencil buffers).
On Broadwell, we can simply state that it's W-tiled in SURFACE_STATE,
and adjust the pitch. This is much easier.
In the surface state code, I chose to handle the "should we sample depth
or stencil?" question separately from the setup for sampling from
stencil. This should make it work with the BindRenderbufferTexImage
hook as well, and hopefully be reusable for GL_ARB_texture_stencil8
someday.

While the GL_ARB_stencil_texturing extension does not allow the creation
of stencil textures, it does allow shaders to sample stencil values
stored in packed depth/stencil textures.
Specifically, applications can call glTexParameter* with a pname of
GL_DEPTH_STENCIL_TEXTURE_MODE and value of either GL_DEPTH_COMPONENT or
GL_STENCIL_INDEX to select which component they wish to sample. The
default value is GL_DEPTH_COMPONENT (for traditional depth sampling).
Shaders should use an unsigned integer sampler (presumably usampler2D)
to access stencil data. Otherwise, results are undefined. Using shadow
samplers with GL_STENCIL_INDEX selected also is undefined behavior.
This patch creates a new gl_texture_object field, StencilSampling, to
indicate that stencil should be sampled rather than depth. (I chose to
use a boolean since I figured it would be more convenient for drivers.)
It also introduces the [Get]TexParameter code to get and set the value,
and of course the extension plumbing.
v2: Also consider textures incomplete when sampling stencil with
non-NEAREST min/mag filters (caught by Eric Anholt).

This only changes radeon and nouveau.
This extension only adds data types that can be passed to, for example,
glTexImage2D. It does not add internal formats. Since you can already
pass GL_FLOAT to glTexImage2D this shouldn't pose any additional issues
with those drivers. Note that r200 and i915 already supported this

This adds an extension called EGL_WL_create_wayland_buffer_from_image
which adds the following single function:
struct wl_buffer *
eglCreateWaylandBufferFromImageWL(EGLDisplay dpy, EGLImageKHR image);
The function creates a wl_buffer which shares its contents with the given
EGLImage. The expected use case for this is in a nested Wayland compositor
which is using subsurfaces to present buffers from its clients. Using this
extension it can attach the client buffers directly to the subsurface without
having to blit the contents into an intermediate buffer. The compositing can
then be done in the parent compositor.
The extension is only implemented in the Wayland EGL platform because of
course it wouldn't make sense anywhere else.
