vf: remove most GPL video filters

Almost all of them had their guts removed and replaced by libavfilter
long ago, but remove them anyway. They're pointless and have been
scheduled for deprecation.

Still leave vf_format (because we need it in some form) and vf_sub (not
sure).

This will break some builtin functionality: lavfi yadif defaults are
different, auto rotation and stereo3d downconversion are broken. These
might be fixed later.

 Available mpv-only filters are:
 
-``crop[=w:h:x:y]``
-    Crops the given part of the image and discards the rest. Useful to remove
-    black bands from widescreen videos.
-
-    ``<w>,<h>``
-        Cropped width and height, defaults to original width and height.
-    ``<x>,<y>``
-        Position of the cropped picture, defaults to center.
-
-``expand[=w:h:x:y:aspect:round]``
-    Expands (not scales) video resolution to the given value and places the
-    unscaled original at coordinates x, y.
-
-    ``<w>,<h>``
-        Expanded width,height (default: original width,height). Negative
-        values for w and h are treated as offsets to the original size.
-
-        .. admonition:: Example
-
-            ``expand=0:-50:0:0``
-                Adds a 50 pixel border to the bottom of the picture.
-
-    ``<x>,<y>``
-        position of original image on the expanded image (default: center)
-
-    ``<aspect>``
-        Expands to fit an aspect instead of a resolution (default: 0).
-
-        .. admonition:: Example
-
-            ``expand=800::::4/3``
-                Expands to 800x600, unless the source is higher resolution, in
-                which case it expands to fill a 4/3 aspect.
-
-    ``<round>``
-        Rounds up to make both width and height divisible by <r> (default: 1).
-
-``flip``
-    Flips the image upside down.
-
-``mirror``
-    Mirrors the image on the Y axis.
-
-``rotate[=0|90|180|270]``
-    Rotates the image by a multiple of 90 degrees clock-wise.
-
-``scale[=w:h:param:param2:chr-drop:noup:arnd``
-    Scales the image with the software scaler (slow) and performs a YUV<->RGB
-    color space conversion (see also ``--sws``).
-
-    All parameters are optional.
-
-    ``<w>:<h>``
-        scaled width/height (default: original width/height)
-
-        :0:      scaled d_width/d_height
-        :-1:     original width/height
-        :-2:     Calculate w/h using the other dimension and the prescaled
-                 aspect ratio.
-        :-3:     Calculate w/h using the other dimension and the original
-                 aspect ratio.
-        :-(n+8): Like -n above, but rounding the dimension to the closest
-                 multiple of 16.
-
-    ``<param>[:<param2>]`` (see also ``--sws``)
-        Set some scaling parameters depending on the type of scaler selected
-        with ``--sws``::

-
-    ``<chr-drop>``
-        chroma skipping
-
-        :0: Use all available input lines for chroma (default).
-        :1: Use only every 2. input line for chroma.

-``dsize[=w:h:aspect-method:r:aspect]``
-    Changes the intended display aspect at an arbitrary point in the
-    filter chain. Aspect can be given as a fraction (4/3) or floating point
-    number (1.33). Note that this filter does *not* do any scaling itself; it
-    just affects what later scalers (software or hardware) will do when
-    auto-scaling to the correct aspect.
-
-    ``<w>,<h>``
-        New aspect ratio given by a display width and height. Unlike older mpv
-        versions or MPlayer, this does not set the display size.
-
-        Can also be these special values:
-
-        :0:  original display width and height
-        :-1: original video width and height (default)
-        :-2: Calculate w/h using the other dimension and the original display
-             aspect ratio.
-        :-3: Calculate w/h using the other dimension and the original video
-             aspect ratio.
-
-        .. admonition:: Example
-
-            ``dsize=800:-2``
-                Specifies a display resolution of 800x600 for a 4/3 aspect
-                video, or 800x450 for a 16/9 aspect video.
-
-    ``<aspect-method>``
-        Modifies width and height according to original aspect ratios.
-
-        :-1: Ignore original aspect ratio (default).
-        :0:  Keep display aspect ratio by using ``<w>`` and ``<h>`` as maximum
-             resolution.
-        :1:  Keep display aspect ratio by using ``<w>`` and ``<h>`` as minimum

-        .. admonition:: Example
-
-            ``dsize=800:600:0``
-                Specifies a display resolution of at most 800x600, or smaller,
-                in order to keep aspect.
-
-    ``<r>``

-``pullup[=jl:jr:jt:jb:sb:mp]``
-    Pulldown reversal (inverse telecine) filter, capable of handling mixed
-    hard-telecine, 24000/1001 fps progressive, and 30000/1001 fps progressive
-    content. The ``pullup`` filter makes use of future context in making its
-    decisions. It is stateless in the sense that it does not lock onto a pattern
-    to follow, but it instead looks forward to the following fields in order to
-    identify matches and rebuild progressive frames.
-
-    ``jl``, ``jr``, ``jt``, and ``jb``
-        These options set the amount of "junk" to ignore at the left, right,
-        top, and bottom of the image, respectively. Left/right are in units of
-        8 pixels, while top/bottom are in units of 2 lines. The default is 8
-        pixels on each side.
-
-    ``sb`` (strict breaks)
-        Setting this option to 1 will reduce the chances of ``pullup``
-        generating an occasional mismatched frame, but it may also cause an
-        excessive number of frames to be dropped during high motion sequences.
-        Conversely, setting it to -1 will make ``pullup`` match fields more
-        easily. This may help process video with slight blurring between the
-        fields, but may also cause interlaced frames in the output.
-
-    ``mp`` (metric plane)
-        This option may be set to ``u`` or ``v`` to use a chroma plane instead of the
-        luma plane for doing ``pullup``'s computations. This may improve accuracy
-        on very clean source material, but more likely will decrease accuracy,
-        especially if there is chroma noise (rainbow effect) or any grayscale
-        video. The main purpose of setting ``mp`` to a chroma plane is to reduce
-        CPU load and make pullup usable in realtime on slow machines.

-``yadif=[mode:interlaced-only]``
-    Yet another deinterlacing filter
-
-    ``<mode>``
-        :frame: Output 1 frame for each frame.
-        :field: Output 1 frame for each field (default).
-        :frame-nospatial: Like ``frame`` but skips spatial interlacing check.
-        :field-nospatial: Like ``field`` but skips spatial interlacing check.
-
-    ``<interlaced-only>``
-        :no:  Deinterlace all frames.
-        :yes: Only deinterlace frames marked as interlaced (default).
-
-    This filter is automatically inserted when using the ``d`` key (or any
-    other key that toggles the ``deinterlace`` property or when using the
-    ``--deinterlace`` switch), assuming the video output does not have native
-    deinterlacing support.
-
-    If you just want to set the default mode, put this filter and its options
-    into ``--vf-defaults`` instead, and enable deinterlacing with ``d`` or
-    ``--deinterlace``.
-
-    Also, note that the ``d`` key is stupid enough to insert a deinterlacer twice
-    when inserting yadif with ``--vf``, so using the above methods is
-    recommended.
