Merge remote-tracking branch 'qatar/master'
* qatar/master: qcelpdec: cosmetics: do not add line break before opening bracket in 'for', 'while', 'if/else', and 'switch' statements. qcelp: check output buffer size before decoding qcelpdec: fix the return value of qcelp_decode_frame(). sipr: fix the output data size check and only calculate it once. Synchronize various 4CCs and codec tags from FFmpeg. qdm2: check output buffer size before decoding Fix out of bound reads in the QDM2 decoder. Check for out of bound writes in the QDM2 decoder. ogg/celt: do not set sample_fmt in the demuxer Conflicts: libavcodec/avcodec.h libavcodec/qdm2.c libavformat/oggparsecelt.c Merged-by: Michael Niedermayer <michaelni@gmx.at>
