Tests that one can sample the given buffer without other mipmap
levels by setting texture filtering accordingly.

v2:
   - compile only on platforms that have drm (Eric)
   - use standard drm definitions for fourcc instead of duplicated
     local (Daniel, Eric)
   - removed irrelevant quote of the spec (Eric)
   - use helper variables for width, height and cpp instead
     of repeating the magic numbers over and over again (Eric)
   - used the same refactored common logic as the mipmap ARGB test

v3 (Eric):
   - use properly linked egl-extension calls

v4 (Eric):
   - add to 'all.tests'
   - removed inclusion of standard EGL entrypoints as there is the
     special dispatcher for the test cases to use

v5 (Eric, Chad):
   - sample using image-external extension
   - fix inclusion in all.tests

v6 (Chad):
   - check for GL error instead of EGL when invoking
     glEGLImageTargetTexture2DOES()
   - allow the test to be skipped if external textures or the
     chosen format are not supported
   - fix the scope of the comment describing the need for closing
     file descriptors in case image creation fails
   - introduce format as command line argument and merge the XRGB
     test here
   - don't invoke glReadPixels() for each pixel separately

v7 (Chad):
   - fix egl-image error checking - do not call eglGetError() twice
     in a row as the first call resets the error
   - convert the boolean returned by 'piglit_probe_image_ubyte()'
     into 'enum piglit_result'
   - re-introduce separate vector for expected results - probe
     expects RGB instead of the BGR of source

v8:
   - add missing fragment shader float precision qualifier
