  avcodec/mpeg4video: Nuke ff_mpeg4_init_rl_intra()
  
  The MPEG-4 decoder can now initialize ff_mpeg4_rl_intra
  directly given that the MPEG-4 encoder no longer wants
  it performed, too.

  avcodec/mpeg4videoenc: Simplify creating LUT
  
  There four cases for the LUT entry: An ordinary entry
  or one of three escaping methods. Three of these methods
  are only rarely possible --they correspond to the 102
  codes of the underlying VLC and so only 102 of 16384 entries
  are possible.
  
  The earlier code would nevertheless try them all for every
  LUT entry and use the best one; the new code meanwhile only
  uses one method (the fallback one (i.e. the worst)) for them all
  and only processes the 102 valid entries afterwards.
  
  The implementation used also means that index_run, max_level
  and max_run of the RLTable are no longer needed; the earlier
  code would initialize said static tables although they are only
  used for a short time to initialize something else.

• avcodec/mpegvideo_enc : Reduce stack usage

  avcodec/mpegvideo_enc: Reduce stack usage
  
  Multiple PutBitContexts are used when encoding partitioned
  frames. When there are multiple candidates for macroblock types,
  multiple states (namely the state before encoding the current MB,
  the best state among the ones already tried and the current one)
  need to be kept; duplicates of the PutBitContexts are among this
  state. The temporary buffers for them are kept on the stack
  in encode_thread() and their size is quite generous (MAX_MB_SIZE
  - 3000 bytes). This commit uses tighter bounds, bringing the
  size of the pb2 buffer down to 15 bytes.

  fftools/makefile: Remove resources from ffprobe
  
  Even though it doesn't have any effect, that line is not needed (yet).
