Clément Bœsch 4181d7741d Merge commit 'facdfe40805559963b5875931af9406ed5ddcd5c' 
* commit 'facdfe40805559963b5875931af9406ed5ddcd5c':
  swscale: Add proper ff_ prefix to init functions

This commit is a noop, see e8c3716064

I'm keeping our ff_sws_ vs ff_ since we use ff_sws_ in other places in
swscale.
