[Piglit] [v2] Tests for image external

[Topi Pohjolainen]

Here I have addressed some of Chad's comments, added yuv tests for
64x66 dimensions and for NV12 format. The mechanism for external
buffer allocation and mapping remains still to be solved.

Topi Pohjolainen (3):
  framework: introduce interface for external buffers
  framework: gbm: support for creating external buffers
  tests/spec: add tests for oes image external
