[Mesa-dev] [PATCH] clover: Add a stub implementation of clCreateImage() v2

[Tom Stellard]

Now that we are uisng the OpenCL 1.2 headers, applications expect all
the OpenCL 1.2 functions to be implemented.

This fixes linking errors with the piglit CL tests.

v2:
  - Use c++ features
  - Fix error code handling
