[Beignet] [PATCH 1/3] refactor the api of intel_driver_share_buffer

[Lu, Guanqun]

I need to add an introduction mail to this series of patches.

This series is used to add the support of binding between libva and opencl. The application can create the corresponding buffer or image from a dri bo handle carried from libva side. And therefore, the application can utilize the power of opencl kernels.

thanks!
