This allows the allocation of buffers used by ffmpeg to come from the gpu.
Then we use MMALRenderer to display the buffers through an opaque pointer.
This avoids two copies of the pixel data (on in kodi and one in transfer to GPU) with software decode.
There is a quite a big performance benefit for this, and allows for example 1080p BluRay decode of MPEG-2 without a hardware codec licence, and improves HEVC support.
