    multiqueue: Ignore time when determining whether sparse stream limits have
been reached

    Basically, sq->max_size.visible is never increased for sparse streams in
    overruncb when empty queue has been found;

    If the queue is sparse it just skip the entire logic determining whether
    max_size.visible should be increased, deadlocking the demuxer.

    What should be done instead is that when determining if limits have been
    reached, to ignore time for sparse streams, as the buffer may be far in the
    future.
