Should address all of the issues brought up in the previous review.

One difference in this implementation is that we now print buffer/buffersink
filters as well, because I couldn't justify omitting them from an implementation
that has nothing to do with ffmpeg.c.

This does unfortunately mean that the output can't *directly* be reused as an
input to -filter_complex without first removing the buffer* entries. In theory
we could add an option to explicitly drop them, but I'm not sold on the idea.
