Merge remote-tracking branch 'qatar/master'
* qatar/master: (22 commits) arm: remove disabled function dct_unquantize_h263_inter_iwmmxt() Remove commented-out call to non-existing function print_pow1(). Do not decode RV30 files if the extradata is too small flashsv: split flashsv_decode_block() off from flashsv_decode_frame(). ppc: remove disabled code libspeexdec: Drop const qualifier to silence compiler warning. libopenjpeg: Drop const qualifier to silence compiler warning. alac: Remove unused dummy code. Remove unused structs and tables. vaapi: do not assert on value read from input bitstream flashsvenc: replace bitstream description by a link to the specification flashsvenc: drop unnecessary cast flashsvenc: improve some variable names and fix corresponding comments flashsvenc: merge two consecutive if-conditions flashsvenc: merge variable declarations and initializations flashsvenc: convert some debug av_log() to av_dlog() flashsvenc: whitespace cosmetics flashsvenc: drop some unnecessary parentheses flashsvenc: fix some comment typos aacps: skip some memcpy() if src and dst would be equal ... Conflicts: libavcodec/vaapi_mpeg2.c libavformat/aviobuf.c Merged-by: Michael Niedermayer <michaelni@gmx.at>
