No functional change here, but this will let us query the image
for an fd handle later.

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.

Just like in GLX, EGL_KHR_create_context requires DRI2 version >= 3, and
EGL_EXT_create_context_robustness requires both DRI2 version >= 3 and the
__DRI2_ROBUSTNESS extension.

With ICS (Android 4.0), several headers and structs are renamed. Define
ANDROID_VERSION so that we can choose a different path depending on the
platform version.
I've tested only softpipe and llvmpipe. r600g is also reported to work.
Add platform_android.c that supports _EGL_PLAFORM_ANDROID. It works
with drm_gralloc, where back buffers of windows are backed by GEM
objects.
In Android a native window has a queue of back buffers allocated by the
server, through drm_gralloc. For each frame, EGL needs to
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After enqueuing, the buffer is no longer valid to EGL.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.

[olv: with assorted minor changes, mostly suggested during the review]
Add rgba_masks to dri2_add_config. When it is non-NULL, the DRI config
is accepted only when the offsets and sizes of the its channels match
rgba_mask.

This enables the egl_dri2 driver to load swrast driver
for software rendering. It could be used when hardware
dri2 drivers are not available, such as in VM.
