Add example to show v4l2 buffer sharing with extension clGetMemObjectFdIntel.
This example captures yuy2 frame directly to cl buffer object by the way
of dma, processed by OpenCL kernel, then convert to nv12 format and
shown by libva.
v2:
Close cl buffer's fd by clCloseMemObjectFdIntel instead of close
function.
v3:
Just use close function, no need of clCloseMemObjectFdIntel.
v4:
Some modifcation of examples/CMakeLists.txt after code rebase.
