Merge remote-tracking branch 'qatar/master'
* 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
