[FFmpeg-devel] [PATCH 00/10] Fix copyright headers of some c files in libavfilter

[Michael Niedermayer]

Hi everyone

I have already during the recent merges noticed that libav
splited out files and removed copyright messages

Heres my attempt at fixing this and other files that lacked
copyright statements since longer as well.
Please review and check that i have not made a mistake
Also help here to review all the other files that lack proper
copyright statements is welcome!
