I think here Michael means something like this, I don't use git so I
don't know which are the corresponding commands, so I'll use the svn
commands.

svn cp libavformat/utils.c libavcodec/avpacket.c

Then you edit libavcodec/avpacket.c so that it will contain *only* the
relevant functions. When copying the file the history for the file will
be inherited by the new file.

Finally you can do:
svn diff libavformat/utils.c libavformat/avformat.h libavcodec/avcodec.h libavcodec/avpacket.c

to get the complete patch.
