* qatar/master:
  mpeg4dec: use unsigned type for startcode in ff_mpeg4_decode_picture_header
  mpeg124: use sign_extend() function
  ac3dec: use get_sbits() instead of manually sign-extending
  4xm: fix signed overflow
  wmavoice: fix a signed overflow
  mpegvideo_enc: fix a signed overflow
  crc: fix signed overflow
  fate: run avconv with -nostats flag
  avtools: add -v as alias for -loglevel
  avconv: always print stats with AV_LOG_INFO
  doc/avconv: add forgotten output/per-stream info to -filter
  avconv: add -stats option to enable/disable printing encoding progress
  avconv: in output_packet() don't set decoded_data_size for video.
  avconv: remove pointless always true condition
  avconv: factorize common code in transcode_init()
  zmbv: remove memcpy() of decoded frame
  mpeg12enc: use sign_extend() function
  h264pred: use unsigned types for pixel values, fix signed overflows
  h264: fix signed overflows in x*0x01010101 expressions
  h264pred: remove unused variables
