Merge remote-tracking branch 'qatar/master'
* qatar/master: (42 commits) swscale: fix signed overflow in yuv2mono_X_c_template snow: fix integer overflows svq1enc: remove stale altivec-related hack snow: fix signed overflow in byte to 32-bit replication adx: rename ff_adx_decode_header() to avpriv_adx_decode_header() avformat: add CRI ADX format demuxer adx: add an ADX parser. adx: move header decoding to ADX common code adx: calculate the number of blocks in a packet adx: define and use 2 new macro constants BLOCK_SIZE and BLOCK_SAMPLES adx: check for unsupported ADX formats adx: simplify encoding by using put_sbits() adx: calculate correct LPC coeffs adx: use 12-bit coefficients instead of 14-bit to avoid integer overflow adx: simplify adx_decode() by using get_sbits() to read residual samples adx: fix the data offset parsing in adx_decode_header() adx: remove unneeded post-decode channel interleaving adx: validate header values adx: cosmetics: general pretty-printing and comment clean-up adx: remove useless comments ...
