> This patch updates the AVHWAccel infrastructure to make it possible  
> to:
> - Get rid of the PixelFormat hacks
> - Get pixels back from GPU memory when the user requested it
> - Fallback implicitly to SW decoding
> - Handle multiple hardware accelerators (e.g. different chips in a  
> single system)
> - Enable user-applications very easily

Changes in this patch:
- svn diff -x -p ;-)
- Drop an extraneous hwaccel->close()
- Add an ff_find_hwaccel_attribute() helper
- Implement checks for the "Get Pixels" capability
