Chromium defined a new GL extension (that isn't registered with Khronos).
We need to add an EGL extension for it, so we can migrate ChromeOS on
Intel systems to use EGL instead of GLX.
http://git.chromium.org/gitweb/?p=chromium/src/third_party/khronos.git;a=commitdiff;h=27cbfdab35c601f70aa150581ad1448d0401f447
The EGL_CHROMIUM_sync_control extension is similar to the GLX extension
OML_sync_control, but only defines one function,
eglGetSyncValuesCHROMIUM, which is equivalent to glXGetSyncValuesOML.

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.

The _EGLSurface struct which is embedded into dri2_egl_surface also contains a
swap interval member so the other member is redundant. Nothing was using it as
far as I can tell.
The Wayland EGL platform now respects the eglSwapInterval value. The value is
clamped to either 0 or 1 because it is difficult (and probably not useful) to
sync to more than 1 redraw.
The main change is that if the swap interval is 0 then Mesa won't install a
frame callback so that eglSwapBuffers can be executed as often as necessary.
Instead it will do a sync request after the swap buffers. It will block for
sync complete event in get_back_bo instead of the frame callback. The
compositor is likely to send a release event while processing the new buffer
attach and this makes sure we will receive that before deciding whether to
allocate a new buffer.
If there are no buffers available then instead of returning with an error,
get_back_bo will now poll the compositor by repeatedly sending sync requests
every 10ms. This is a last resort and in theory this shouldn't happen because
there should be no reason for the compositor to hold on to more than three
buffers. That means whenever we attach the fourth buffer we should always get
an immediate release event which should come in with the notification for the
first sync request that we are throttled to.
When the compositor is directly scanning out from the application's buffer it
may end up holding on to three buffers. These are the one that is is currently
scanning out from, one that has been given to DRM as the next buffer to flip
to, and one that has been attached and will be given to DRM as soon as the
previous flip completes. When we attach a fourth buffer to the compositor it
should replace that third buffer so we should get a release event immediately
after that. This patch therefore also changes the number of buffer slots to 4
so that we can accomodate that situation.
If DRM eventually gets a way to cancel a pending page flip then the compositors
can be changed to only need to hold on to two buffers and this value can be
put back to 3.
This also moves the vblank configuration defines from platform_x11.c to the
common egl_dri2.h header so they can be shared by both platforms.
This lets us allocate color buffers as __DRIimages and pass them into
the driver instead of having to create a __DRIbuffer with the flink
that requires.

All callers now use the more correct rgba mask mechanism for filtering
out mathcing DRI configs. Even if depth and buffer size match, the
color component layout can be different, or in case or ARGB8888 and
ARGB2101010 the color components can even be different sizes.
Since anything that the depth check would reject is also rejected by
the rgba mask comparison, the depth parameter is redundant and not
specific enough. We should probably have removed it when the rgba
masks argument was introduced, but better late than never.

We used to keep the color buffers in the dri_buffers array and
swap __DRI_BUFFER_BACK_LEFT and __DRI_BUFFER_FRONT_LEFT around there
and swap third_buffer in in case we needed to triple buffer. That
gets a little fidgety with all the swaps, so lets use the
color_buffers pool like the gbm platform does. We track the color buffers,
their corresponding wl_buffer and locked status here and just plug
a free one into dri2_surf->buffers when we need to.
This is a nice clean-up in itself, but it also sets us up to track
buffer age in the color_buffers structs.

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.
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.

In Android a native window has a queue of back buffers allocated by the

dequeue the next back buffer
render to the buffer
enqueue the buffer
After enqueuing, the buffer is no longer valid to EGL. A window has no
depth buffer or other aux buffers. They need to be allocated locally by
EGL.
