With commit e59fa4c46c8("dri2: release texture image.") we updated the
extension without bumping the version number. The patch itself added an
interface required to enable texture_from_pixmap on certain platforms.
The new code was effectively never build, as it depended on
__DRI_TEX_BUFFER_VERSION >= 3, which never came to be in upstream mesa.
This commit bumps the version number, drops the __DRI_TEX_BUFFER_VERSION
checks and resolves all the build conflicts. Additionally it add a version
check as egl and dri3, as require version 2 of the extension which does
not have the releaseTexBuffer hook.

Internally, much of the EGL code uses EGLNativeDisplayType,
EGLNativeWindowType, and EGLPixmapType. However, the EGLNative type
often does not match the variable's actual type.
The concept of EGLNative types are a bad match for Linux, as explained
below. And the EGL platform extensions don't use EGLNative types at all.
Those extensions attempt to solve cross-platform issues by moving the
EGL API away from the EGLNative types.
The core of the problem is that eglplatform.h can define each EGLNative
type once only, but Linux supports multiple EGL platforms.
To work around the problem, Mesa's eglplatform.h contains multiple
definitions of each EGLNative type, selected by feature macros. Mesa
expects EGL clients to set the feature macro approrpiately. But the
feature macros don't work when a single codebase must be built with
support for multiple EGL platforms, *such as Mesa itself*.
When building libEGL, autotools chooses the EGLNative typedefs based on
the first element of '--with-egl-platforms'. For example,
'--with-egl-platforms=x11,drm,wayland' defines the following:
typedef Display* EGLNativeDisplayType;
typedef Window EGLNativeWindowType;
typedef Pixmap EGLNativePixmapType;
Clearly, this doesn't work well for Wayland and GBM. Mesa works around
the problem by casting the EGLNative types to different things in
different files.
For sanity's sake, and to prepare for the EGL platform extensions, this
patch removes from egl/main and egl/dri2 all internal use of the
EGLNative types. It replaces them with 'void*' and checks each explicit
cast with a static assertion. Also, the patch touches egl_gallium the
minimal amount to keep it compatible with eglapi.h.

egl_dri2.c:dri2_terminate() handled terminating X11 and DRM displays.
The Wayland platform implemented its own dri2_wl_terminate(), which was
nearly a copy of the common one.
To implement the EGL platform extensions, we either need to dispatch
eglTerminate per display or define a common implementation for all
platforms. This patch chooses consolidation. It removes
dri2_wl_terminate() by folding it into the common dri2_terminate().
It was necessary to invert the `if (disp->PlatformDisplay == NULL)` and
the switch statement because, unlike DRM and X11, Wayland's terminator
performed action even when EGL didn't own the native display. In the
inversion, I replaced `disp->PlatformDisplay == NULL` with
`dri2_dpy->own_device` because the two expressions are synonymous, but
the latter's meaning is clearer.

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.

commit 3998f8c6b5
Author: Ralf Jung <post@ralfj.de>
Date: Tue Apr 9 14:09:50 2013 +0200
egl/x11: Fix initialisation of swap_interval
This little code snippet near the bottom of dri2_add_config,
if (double_buffer) {
...
conf->base.MinSwapInterval = dri2_dpy->min_swap_interval;
conf->base.MaxSwapInterval = dri2_dpy->max_swap_interval;
}
it never did what it claimed to do. The assignment never changed the value
of conf->base.MaxSwapInterval, because dri2_dpy->max_swap_interval was,
until the above exposing commit, unitialized here. That is,
conf->base.MaxSwapInterval was 0 before and after assignment. Ditto for
the min swap interval.
Above the troublesome code snippet, the call to _eglFilterArray rejects
the config as unmatching if its swap interval bounds differ from the base
config's. Before the exposing commit, at the call to _eglFilterArray, the
swap interval bounds were always [0,0], and hence no config was rejected
due to swap interval.
After the exposing commit, _eglFilterArray incorrectly rejected some
configs, which prevented dri2_egl_config::dri_double_config from getting
set for the rejected config, which resulted in a NULL pointer getting
passed into dri2CreateNewDrawable, and then segfault.
The solution: set the swap interval bounds before _eglFilterArray.

Previously only the 32-bit X visual would match the 32-bit RGBA8888
configs. This resulted in every config with alpha getting the "magic"
visual whose alpha is used by the compositor. This also resulted in no
multisample visuals being advertised. How many ways could we lose?
This patch inverts the problem... now you can't get the visual with
alpha used by the compositor even if you want it. I think we need to
invent a new value for EGL_TRANSPARENT_TYPE that apps can use to get
this. I'm surprised that there isn't already a choice for
EGL_TRANSPARENT_ALPHA.

This plumbing is added in order to comply with the EGL_KHR_create_context
spec. According to the EGL_KHR_create_context spec, it is illegal to call
eglCreateContext(EGL_CONTEXT_MAJOR_VERSION_KHR=3) with a config whose
EGL_RENDERABLE_TYPE does not contain the EGL_OPENGL_ES3_BIT_KHR. The
pertinent
portion of the spec is quoted below; the key word is "respectively".
* If <config> is not a valid EGLConfig, or does not support the
requested client API, then an EGL_BAD_CONFIG error is generated
(this includes requesting creation of an OpenGL ES 1.x, 2.0, or
3.0 context when the EGL_RENDERABLE_TYPE attribute of <config>
does not contain EGL_OPENGL_ES_BIT, EGL_OPENGL_ES2_BIT, or
EGL_OPENGL_ES3_BIT_KHR respectively).

When creating an EGLImage from a struct wl_buffer * this ensures
that we create an XRGB8888 image if the wayland buffer doesn't have an
alpha channel. To determine if a wl_buffer has a valid alpha channel
this patch adds an internal wayland_drm_buffer_has_alpha() function.
It's important to get the internal format for an EGLImage right so that
if a GL texture is later created from the image then the GL driver will
know if it should sample the alpha from the texture or flatten it to
a constant of 1.0.
This avoids needing fragment program workarounds in wayland compositors
to manually ignore the alpha component of textures created from wayland
buffers.
