From: Rob Clark <rob@ti.com>

In cases where the GPU can natively handle certain YUV formats,
eglQueryWaylandBufferWL() can return the value EGL_TEXTURE_EXTERNAL_WL
and the compositor will treat the buffer as a single egl-image-external.

See:
http://www.khronos.org/registry/gles/extensions/OES/OES_EGL_image_external.txt

v1: original
v2: rename EGL_TEXTURE_EXTERNAL_OES -> EGL_TEXTURE_EXTERNAL_WL and query
    for the extension
v3: fix build without updated mesa headers, if EGL_TEXTURE_EXTERNAL_WL
    #define is missing from older mesa headers.

This patch is clearly missing something. :-)
The following patches won't apply.
