With this patch Wayland clients can now ask EGL for RGB 565 format buffers
and attach them to a Wayland compositor.

Now that libEGL has been fixed to not leak all kinds of symbols, gbm
links to its own copy of the libwayland-drm.a helper library. That means
we can't rely on comparing the addresses of a static vtable symbol in that
library to determine if a wl_buffer is a wl_drm_buffer. Instead, we
move the vtable into the wl_drm struct and use that for comparing.

libEGL was incorrectly exporting *all* symbols, public and private.
This patch adds -fvisibility=hidden to libEGL's linker flags to ensure
that only symbols annotated with __attribute__((visibility("default")))
get exported.
Sanity-checked with libEGL's builtin DRI2 driver and the i965 DRI driver
by running Piglit on X/EGL and by running weston-gears on Weston as an
X client.
Sanity-checked with libEGL's Gallium driver (which is not built-in) and
the swrast Gallium driver by running es2gears_x11.
Kristian reviewed the symbol diff in `nm libEGL.so`.

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.

This gets referenced before we get to generate the header files, so just include the
enum that we need and don't include the generated header.

This generalizes and replaces gbm_bo_create_for_egl_image. gbm_bo_import
will create a gbm_bo from either an EGLImage or a struct wl_buffer.

This lets us specify the plane to create the image for for multiplanar
wl_buffers.

We're going to extend this to support multi-plane buffers, so pass this
to the driver so it can access the details.

Commit 272bc48976 removed the damage implementation for the
wl_buffer_interface because that has been removed from git master of
Wayland. However this breaks building with the 0.85 branch of Wayland
because it would end up initialising the struct incorrectly.
For the time being it's quite convenient for some compositors to track
the 0.85 branch of Wayland because the protocol is stable but they
will also want to track the master branch of Mesa so that they can use
the gbm surface changes.
This patch adds a compile-time check for the version of Wayland so
that it can work with either Wayland master or the 0.85 branch.
krh: Edited to also account for API changes in 6802eaa68, which
removes the timestamp argument from wl_resource_destroy().

This is a related fix for the Wayland change:
commit 83685c506e76212ae4e5cb722205d98d3b0603b9

Remove wl_buffer.damage and simplify shm implementation
Apparently, this should also fix a memory leak. When wl_buffer.damage
was removed from Wayland and Mesa was not fixed, wl_buffer.destroy ended
up in the (empty) damage function instead of calling
wl_resource_destroy().
Spotted during build as:

wayland-drm.c:82:1: warning: excess elements in struct initializer

So we can use the wayland scanner makro, which is way
better than our previous runtime-pkgconfig hack.

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.
krh: Edited to use wl_buffer_get_format() instead of wl_buffer_has_alpha().

Us poor souls who cross compile mesa want to be able to specify which pkg-config to pick, or at least just change one place.
