Initializing DASH streams is currently slow, because each individual
stream is opened and probed sequentially. With DASH streams often
having somewhere between 10-20 streams, this can easily take up to
half a minute on slow connections.

This patch adds an "init_threads" option, specifying the max number
of threads to use. Multiple worker threads are spun up to massively
bring down init times.
