avcodec/utils: allocate a line more for VC1 and WMV3
Fixes: out of array read on 32bit Fixes: 54857/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_VC1_fuzzer-5840588224462848 The chroma MC code reads over the currently allocated frame. Alternative fixes would be allocating a few bytes more at the end instead of a whole line extra or to adjust the threshold where the edge emu code is activated Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc> (cherry picked from commit 01636a63d452c592ece35af6f72bb7affcad58f2) Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
