Also check return value of av_frame_copy() in passthrough mode, so that
if a copy fails (as it did here, because bitdepth didn't match), the filter
doesn't return success, which would mean sending an uninitialized framebuffer
further down the filtergraph.

Also add von kries whitepoint adaptation, and add 'identity' to turn
whitepoint adaptation off.

Also add some documentation for each function to colorspacedsp.h.

Update print mode output header line format to be more consistent with
other log output of FFmpeg. The printf-modifiers have been inspired by
the showinfo filter.
