We also reuse EGL_TEXTURE_RGBA and EGL_TEXTURE_RGB, adding only the new
planar YUV texture formats: EGL_TEXTURE_Y_U_V_WL, EGL_TEXTURE_Y_UV_WL and
EGL_TEXTURE_Y_XUXV_WL.

We factor out all the EGL book-keeping into dri2_create_image() and
simplify the wayland case by using dupImage.

libglapi.so, libGL.so, libGLESv2.so, libGLESv1_CM.so must all
come from the same version of Mesa or bad things may happen.

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().

We don't want to set the pixmap bit in the EGL config if the DRI
config we're adding is a double buffered config. However, don't clear
any other bits the platform might pass in in the surface_type
argument.
Set ctx->WindowRenderBuffer to EGL_BACK_BUFFER. As EGL_WINDOW_BIT of a
config is set only when there is dri_double_buffer, that makes sure
window surfaces are always double-buffered and contexts will render to
the back buffer.

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After enqueuing, the buffer is no longer valid to EGL.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.

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.

When an app loads libEGL.so dynamically with RTLD_LOCAL, loading DRI
drivers would fail because of missing glapi symbols. This commit makes
egl_dri2 load libglapi.so with RTLD_GLOBAL to export glapi symbols for
future symbol resolutions.
The same trick can be found in GLX. However, egl_dri2 can only do so
when --enable-shared-glapi is given. Because, otherwise, both libGL.so
and libglapi.so define glapi symbols and egl_dri2 cannot tell which
library to load.
The idea is to be able to match a driver using the following order
try egl_gallium with hw renderer
try egl_dri2
try egl_gallium with sw renderer
try egl_glx
given the module list
egl_gallium
egl_dri2
egl_glx
For that, UseFallback initialization option is added. The module list
is matched twice: with the option unset and with the option set. In the
first pass, egl_gallium skips its sw renderer and egl_glx rejects to
initialize since UseFallback is not set. In the second pass,
egl_gallium skips its hw renderer and egl_dri2 rejects to initialize
since UseFallback is set. The process stops at the first driver that
initializes the display.
