    mssdemux: implement snap seeking

    Implement snap seek flags handling in stream_seek to allow the
    parent class to handle it for us

    tests: dashdemux: add tests for snap flags seeking

    Similar to HLS but DASH has the extra issue that it can have
    multiple streams so snapping can be tricky as streams usually
    won't be aligned.

    For now, those tests handle the case of only having a single
    stream.

    adaptivedemux: handle snap seeks

    Adaptive demuxers need to start downloading from specific positions
    (fragments) for every stream, this means that all streams can snap-seek
    to a different position when requested. Snap seeking in this case will
    be done in 2 steps:

    1) do the snap seeking on the pad that received the seek event and
       get the final position

    2) use this position to do a regular seek on the other streams to
       make sure they all start from the same position

    More arguments were added to the stream_seek function, allowing better
control
    of how seeking is done. Knowing the flags and the playback direction allows
    subclasses to handle snap-seeking.
    And also adds a new return parameter to inform of the final
    selected seeking position that is used to align the other streams.
