video: remove user-controllable PTS sorting (--pts-association-mode)

Browse Source 
Useless. Sometimes it might be useful to make some extremely broken
files work, but on the other hand --no-correct-pts is sufficient for
these cases.

While we still need some of the code for AVI, the "auto" mode in
particular inflated the size of the code.

.. warning:: Using realtime priority can cause system lockup.
``--pts-association-mode=<decode|sort|auto>``
Select the method used to determine which container packet timestamp
corresponds to a particular output frame from the video decoder. Normally
you should not need to change this option.
:decoder: Use decoder reordering functionality. Unlike in classic MPlayer
and mplayer2, this includes a DTS fallback. (Default.)
:sort: Maintain a buffer of unused pts values and use the lowest value
for the frame.
:auto: Try to pick a working mode from the ones above automatically.
You can also try to use ``--no-correct-pts`` for files with completely
broken timestamps.
``--force-media-title=<string>``
Force the contents of the ``media-title`` property to this value. Useful
for scripts which want to set a title, without overriding the user's
