The headers got removed because the ffmpeg source tree is no place for 
third party library headers. Yes, avisynth was an exception, not anymore.

Actually with the change it got documented that you need to install the 
headers.

Sometimes you have to follow up on your compile scripts to be able to 
build the newest ffmpeg. Considering that how easy avisynth upstream made 
it to install the headers, I am sure this is only a small nuisance.
