Guillaume Desmottes 7be54ad091 omxvideoenc: implement dmabuf export on input buffers
Propose pool upstream so input buffers can be allocated by the port and
exported as dmabuf.

The actual OMX buffers are allocated when the pool is activated, so we
don't end up doing useless allocations if the pool isn't used.
