  lavf/webvttdec: use private option to specify WebVTT kind
  
  WebVTT subtitle tracks have four kinds. Certain downstream muxers
  (such as for WebM) need to know which WebVTT kind this is, in order to
  specify the codec id of the output track.
  
  A new private input option, "-kind", has been added to the WebVTT
  demuxer.  It accepts as a value any of "subtitles" (the default),
  "captions", "descriptions", and "metadata".  The kind option value is
  used to assign a value to the stream disposition flag, to which four
  new values have been added, corresponding the four WebVTT kinds.

  lavf: add AV_DISPOSITION flags for WebVTT text track kinds
  
  There are 4 separate WebVTT text track kinds: subtitles (the default
  if not otherwise specified), captions, descriptions, and metadata.
  The WebM muxer needs to know which WebVTT text track kind this is, in
  order to synthesize the correct track type and codec id.
  
  To allow a demuxer to indicate the text track kind of the input, a new
  set of AV_DISPOSITION flag values has been added, corresponding to
  each of the non-default text track kind values.
