demux: make demux_open() private

I always wanted to get rid of this, because it makes the ownership rules
for the stream pointer really awkward. demux_edl.c was the only
remaining user of this. Replace it with a semi-clever idea: the init
segment shit can be used to pass the "file" contents as memory block,
and "memory://" itself provides an empty stream. I have no idea if this
actually works, because I didn't immediately find a test stream (would
have to be some youtube DASH shit).
