  avcodec/sanm: implement STOR/FTCH for ANIMv1
  
  Handle STOR/FTCH the same way the RA1 game engine does:
  On STOR, save the next following FOBJ (not the decoded image)
  in a buffer; decode it on FTCH.
  The RA1 codecs and the fobj handler now take an explicit
  GetByteContext in order to be able to replay stored data.
  
  Used extensively by Rebel Assault 1 for e.g. backgrounds and
  the cockpit overlay.
  
  For ANIMv2 keep the current system to store the decoded image, as
  replaying a FOBJ would not work with codecs37/47/48 due to sequence
  violations.

  Nothing in this decoder would break if the generic code were to be
  changed to allow slice "threading" with only one thread.

  avcodec/mpeg12dec: Use saturated addition when combining error_count
  
  Fixes undefined integer overflows. The overflows could always
  happen, yet before 4d8b706b1d33e75eb30b289c152280d4535c40e6
  it was not undefined because the code implicitly used atomic
  types, for which signed integer overflow is defined.
