[Glamor] [PATCH] autoconf: configuration for egl, gbm and dri3 support

[Gaetan Nadon]

A prerequisite is the patch series entitled:
    "Bring package up to spec and fix minor issues"

Additional tests have been added for the dri3 glamor code to use:
    Declaration of DRM_FORMAT_ARGB8888
    Declaration of EGL_KHR_image is declared
    Declaration of EGL_KHR_gl_texture_2D_image
    Declaration of EGL_EXT_image_dma_buf_import
    EGLNativePixmapType must refer to a gbm_bo structure
    Libgbm is at version 9 or greater

The tests are performed if the libraries/headers are present, they are not
limited to the dri3 support context. They are reusable.

One missing behaviour has been added. When the user explicitly requests
dri3 support and it can not be provided, abort the configuration.
This is the case when user types "--enable-glamor-dri3".

Here are the test cases and their configure output as a reference:
