[Piglit] [v6] Tests for EXT_image_dma_buf_import

[Topi Pohjolainen]

Here are some tests for the dma buffer importing. These are mostly
things specifically listed down in the spec itself regarding
attributes and their values. This version two adds three additional
tests for sampling packed RGB, but testing of more complex planar
(YUV) formats is left until one has the sampling support in place
provided by the image external extension.

I augmented the framework to provide platform independent interface
for creating and releasing the target buffers. I hope to re-use the
logic for the external image testing later on.

v2-v4:
   - clarifications on closing the buffers
   - added tests sampling RGB formatted buffers
   - check for EGL extensions, not for GL (added a utility for this)

v5:
   - split tests into individual commits
   - introduced common header for drm fourcc formats

v6:
   - various fixes according to review comments from Eric, Chad,
     Daniel and Ken
   - refactored dri2-authentication from Chad's revision of dma
     buffer support into its own patch. I had fixes for other
     review comments already in my version of the base patch.


Chad: Please check if you agree into conditionally including the
      authentication support. I'm fine having it as you proposed
      originally. I just couldn't get it working on my Ubuntu
      laptop, and not being too familiar with the mechanism in
      general I thought better getting stuff for review as I have
      revisioned the series heavily.

Eric,Chad,Daniel: In my system subsequent call of 'close()'
                  against the same file descriptor returns -1
		  instead of EBADF. Hence I just check that the
		  return value differs from zero.
