This adds explicit names for softpipe and llvmpipe to the gallium driver

clarify how lavapipe depends on (just) llvmpipe, and we make it possible
to build llvmpipe without softpipe.

The EGL_WL_create_wayland_buffer_from_image is still used in WPE WebKit.
There is work in progress to continue adoption of DMA-BUF usage inside
WebKit which will eventually render the extension unneeded; but in the
meantime an update to a version of Mesa without the extension would
render applications using WPE WebKit unusable.

EGL 1.5 specification requires to not match on EGL_NATIVE_VISUAL_ID.
EGL_MESA_x11_native_visual_id extension allows us to remove this
restriction for X11, where we need to match EGL_NATIVE_VISUAL_ID to find
visuals which allow blending.
The reasoning is that on X11, compositors use the visual as "magic bit"
to decide whether to alpha-blend surface contents.
Unlike on most (all?) other windowing systems, requesting an alpha channel
for the config alone does not already imply blending on the compositor
level.
Thus, in order to allow clients to explicitly request configs with
"magic bit" and, similar to GLX, to order configs in a way so clients
not requesting alpha-blending do not get it by accident, do match
visual ids.
Note that one consequence of this is that more configs get
reported to clients.

This extension was originally intended to complement
EGL_WL_bind_wayland_display.
The idea behind bind_wayland_display was that libEGL.so on the server
side could register Wayland extensions for libEGL.so on the client side
to use to create buffers, with eglQueryWaylandBufferWL being used to
query the buffer properties, and EGL_WAYLAND_BUFFER_WL added as an
EGLImage target for texturing.
eglCreateWaylandBufferFromImageWL was then to be used for nested
compositors to perform passthrough: it would take an EGLImage created by
the magical libEGL secret handshake, and make it usable in the parent
compositor by doing the same secret handshake again.
Since that original idea, we've just standardised dmabuf across the
Wayland ecosystem instead. The last known user of this extension was a
sample client in the Weston tree, which was broken quite some years ago
and never ported to the Meson build system when we moved.
Given it won't affect anyone, let's just remove this extension so no-one
thinks it would be a good idea to use it.

EGL_EXT_create_context_robustness provides separate knobs for device
reset strategy and robust buffer access. As there is no separate query
for both piecies of functionality, devices which do not support robust
buffer access need to reject contexts created with that flag with
EGL_BAD_CONFIG.
Given that EGL can't do cap queries, we create a fake extension entry in
the EGLDisplay to cover whether the device can do robust buffer access
or just device-reset queries.

When `MESA_LOADER_DRIVER_OVERRIDE` is set to `zink` and the display
initialization fails, fallback to software rendering.
The error was reported in #10123 and it can be reproduced with:
$ MESA_LOADER_DRIVER_OVERRIDE=zink eglinfo
`eglinfo` would crash in `dri2_display_release()` because of
`assert(dri2_dpy->ref_count > 0)`.
After bisecting the error to commit 8cd44b8843 ("egl/glx: add
autoloading for zink"), I found out that, before this change, the
display was set to initialized even when `_eglDriver.Initialize(disp)`
failed:
disp->Options.Zink = env && !strcmp(env, "zink");
// disp->Options.Zink is true
if (!_eglDriver.Initialize(disp)) {
[...]
// Zink initialization has failed at this point
// However, success is set to true:
bool success = disp->Options.Zink;
if (!disp->Options.Zink && !getenv("GALLIUM_DRIVER")) {
[...]
}
// Software initialization is ignored because success is true
if (!success) {
[...]
}
}
// The display is set as initialized even though it shouldn't
disp->Initialized = EGL_TRUE;

In commit 1396dc1c a new output field was added as a parameter, but this
is a problem since the signature of the function are not versionned.
The flush function didn't have a versionned output struct. So what I'm
proposing here is that if the version of the input argument is new enough
(bumped to 2 here), then we re-use the existing argument, which until now
was directly a pointer to GLsync, and instead use it as a pointer to a
versioned struct.
We're just changing one pointer type to another, so in C, this should
be fine AFAIK.
