This has not even had an attempt at implementation. If you asked for
renderer 0 - which, the spec implies, should always work - then
dri2_convert_glx_attribs would fail, we'd silently fall back to creating
an indirect context, and xserver would also not recognize the attribute
and would throw BadValue at you.
The API would be difficult to use in any case, since there's no way to
enumerate how many renderers the screen has. I'd be tempted to add that
by defining:
glXQueryRendererIntegerMESA(dpy, screen,
/* renderer = */ -1,
0, &value);
to return the number of renderers, but a new entrypoint might be
cleaner. Still, better to not specify it at all than to lie about it.

In one place we say, if GLES isn't supported then the profile version
will be 0.0. Then later we say, if the GLES profile extension isn't
supported then GLX_RENDERER_OPENGL_ES_PROFILE_VERSION_MESA is not
mentioned in the spec. A strict reading of the latter would mean that
GLX_RENDERER_OPENGL_ES_PROFILE_VERSION_MESA is not a recognized token,
and the query should instead return False.
The implementation does not check for the GLES profile extensions, and
the additional complexity doesn't seem worth it. Removing the
interaction text makes the spec match the implementation.

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.

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.
The enumerated values are currently allocated from Intel's range.
v2: Fix a typo. Update the list of functions to which the new enums can
