  h264: fix decoding multiple fields per packet with slice threads
  
  Since we only know whether a NAL unit corresponds to a new field after
  parsing the slice header, this requires reorganizing the calls to slice
  parsing, per-slice/field/frame init and actual decoding.
  
  In the previous code, the function for slice header decoding also
  immediately started a new field/frame as necessary, so any slices
  already queued for decoding would no longer be decodable.
  
  After this patch, we first parse the slice header, and if we determine
  that a new field needs to be started we decode all the queued slices.
