Add frame procedure for retrieving image data from accelerated frames in standard format.
Frame grabbing didn't work for frame image formats besides YV12 and YUY2 as decoded data
is not stored in accelarated frames. Some acceleration APIs allow to read back decoded
image data in the common standard formats mentioned above. The new procedure allows the
vo_driver to provide a way for retrieving image data which can later be utilized by
_x_get_current_frame_data() to implement frame grabbing for accelerated frames.
