When a client frame callback is executed and the client starts rendering
again, the egl event queue might not have been dispatched so that the
buffer release event for the previous frame hasn't been processed. In
that case a third buffer is allocated, even though it would be possible
to reuse the buffer that was just released.
The wl_display_dispatch_queue_pending() entry point is available from
wayland-client 1.0.2, so require that in configure.ac. Also, just
let the pkg-config macro throw its own error, which will show what version
we were looking for and failed to find.
Note: This is a candidate for stable branches.

Commit ca3ed3e024 fixed the problem where
eglMakeCurrent would trigger a getbuffer callback that then breaks the
following wl_egl_window_resize() call. However, we still need to
invalidate buffers in eglSwapBuffers, since in wayland we always swap
buffers, so the dri driver needs to come out and ask us for the next buffer
after each swapbuffer.
Note: this is a candidate for stable branches.

We used to invalidate the drawable after a call to eglSwapBuffers(),
so that a wl_egl_window_resize() would take effect for the next frame.
However, that leads to calling dri2_get_buffers() when eglMakeCurrent()
is called with the current context and surface, and a later call to
wl_egl_window_resize() would not take effect until the next buffer
swap.
Instead, add a callback from wl_egl_window_resize() back to the wayland
egl platform, and invalidate the drawable only when it is resized.
This solves a bug on wayland clients when going back to windowed mode
from fullscreen when clicking a pop up menu, where the window size
after this would be the fullscreen size.
Note: this is a candidate for stable branches.

When dri2CreateContextContextAttribs failed, eglCreateContext returned
NULL yet set the error code to EGL_SUCCESS! The problem was that
eglCreateContext ignored the error code returned by
driCreateContextAttribs.

If a frame callback is not destroyed when destroying a surface, its
handler function will be invoked if the surface was destroyed after the
callback was requested but before it was invoked, causing a write on
free:ed memory.
This can happen if eglDestroySurface() is called shortly after
eglSwapBuffers().
Note: This is a candidate for stable branches.

It doesn't provide the cross-process buffer sharing that a window system
pixmap could otherwise support and we don't have anything left that uses
this type of surface.
The 0.99.0 Wayland release changes the event API to provide a thread-safe
mechanism for receiving events specific to a subsystem (such as EGL) and
we need to use it in the EGL platform.
The Wayland protocol now also requires a commit request to make changes
take effect, issue that from eglSwapBuffers.
Version 12 of the EGL_KHR_create_context spec changed this behavior.
NOTE: This is a candidate for the 9.0 branch

The invalidate event support is a careful dance between driver and loader,
where both have to say they can handle it, and then the loader reports
invalidate events for the driver so the driver can do the optimization.
The EGL code doesn't report __DRIuseInvalidateExtension to the driver, so it
has no responsibility to call the driver's invalidate function, and the driver
is doing the glViewport hack because it assume. This is not
the only time invalidate would need to be called (we need it *any* time an
invalidate event comes down the pipe, but we don't watch for them), so just
stop calling the driver's function.

This behavior mostly matches glx_dri2. It's slightly complicated in
comparison because EGL exposes the implementation limits in the EGL config.
Note that platform_x11 was the only one setting swap_available, so the move of
the MaxSwapInterval into it is appropriate.

These calls allowed Xlib to use a custom memory allocator, but Xlib has
used the standard C library functions since at least its initial import
into git in 2003. It seems unlikely that it will grow a custom memory
allocator. The functions now just add extra overhead. Replacing them
will make future Coccinelle patches simpler.

As discussed with Kristian on #wayland. Pushes the decision of components into
the dri driver giving it greater freedom to allow t to implement YUV samplers
in hardware, and which mode to use.
This interface will also allow drivers like SVGA to implement YUV surfaces
without the need to sub-allocate and instead send 3 seperate buffers for each
channel, currently not implemented.
I have tested these changes on Gallium Svga. Scott tested them on both intel
and Gallium Radeon. Kristan and Pekka tested them on intel.

Uses libkms instead of dri image cursor. Since this is the only user of the
DRI cursor and write interface we can remove cursor surfaces entirely from
the DRI interface and as a consequence also from the Gallium interface as
well. Tho to make everybody happy with this it would probably should add a
kms_bo_write function, but that is probably wise in anyways.
The only downside is that it adds a dependancy on libkms, this could how ever
be replaced with the dumb_bo drm ioctl interface.
