Emil Velikov 0c4eef6a2c egl: remove remaining EGL_MESA_copy_context skeleton
With earlier commit (7a58262e58 egl: Remove skeleton implementation of
EGL_MESA_screen_surface) we've removed the skeleton implementation of
eglCopyContextMESA(). Just like EGL_MESA_screen_surface this extension
was never implemented in mesa.

Emil Velikov f9bf9133cc egl: fix the EGL_MESA_image_dma_buf_export header declarations
Similar to other EGL extensions - guard the function prototypes by
EGL_EGLEXT_PROTOTYPES as the libEGL library does (should) not provide
the symbols statically.

Instead users should call eglGetProcAddress, which returns the function
pointer. The latter of which was missing the type declaration (typedef).

Adam Jackson 7a58262e58 egl: Remove skeleton implementation of EGL_MESA_screen_surface
No backend wires this up to anything, and the extension spec has been
marked obsolete for 4+ years.

Dave Airlie 8f7338f284 egl: add initial EGL_MESA_image_dma_buf_export v2.4
At the moment to get an EGL image to a dma-buf file descriptor,
you have to use EGL_MESA_drm_image, and then use libdrm to
convert this to a file descriptor.

This extension just provides an API modelled on EGL_MESA_drm_image,
to return a dma-buf file descriptor.

v2: update spec for new API proposal
add internal queries to get the fourcc back from intel driver.

v2.1: add gallium pieces.

v2.2: add offsets to spec and API, rename fd->fds, stride->strides
in API. rewrite spec a bit more, add some q/a

v2.3:
add modifiers to query interface and 64-bit type for that (Daniel Stone)
specifiy what happens to num fds vs num planes differences. (Chad Versace)

v2.4:
fix grammar (Daniel Stone)

Neil Roberts 551d459af4 Add the EGL_MESA_configless_context extension
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.

Neil Roberts 5cddb1ce3c wayland: Add an extension to create wl_buffers from EGLImages
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.

Since Wayland 1.2, struct wl_buffer and a few functions are deprecated.

References to wl_buffer are replaced with wl_resource and some getter
functions and calls to deprecated functions are replaced with the proper
new API. The latter changes are related to resource versioning.
