Since we're talking about API cleanup anyway. What is this function?

A "stream" isn't a very useful concept. Why do demuxers want to know
whether the input is a stream? They more likely want to know whether
the input is seekable (like HTTP/1.1 with RangeRequest vs. HTTP/1.0 or
a pipe/fifo), or whether seeking - if supported at all - is slow (like
HTTP/1.1 with RangeRequest vs. a local seekable file). I see it used
in a variety of different demuxers with a different implied meaning
(seeking is slow vs. seeking is unsupported), and that is bad.

Also, no doxy so apparently even we don't know what it means.
