I have difficulty imaging a addrlen that does not fit in a 32bit int.

Ill gladly approve a patch using int, if you want to use something else you
will have to quote posix & iso C to proof that our AVERROR codes fit in a
ssize_t also this would be the first ssize_t in ffmpeg, i really have a
bad feeling about this.
