| * opus: Fix typo causing overflow in silk_stabilize_lsfAndreas Cadhalpun2015-12-16
| | | | | | | | | | | | | | | | | | | | Due to this typo max_center can be too large, causing nlsf to be set to too large values, which in turn can cause nlsf[i - 1] + min_delta[i] to overflow to a negative value, which is not allowed for nlsf and can cause an out of bounds read in silk_lsf2lpc.

Conflicts: Changelog configure libavcodec/version.h Fate tests pass with both avresample as well as swresample based opus decoder, but are disabled (reference files are very large so i want to think a day or 2 about if theres an alternative or if they could be avoided, they also dont match the official samples) Merged-by: Michael Niedermayer <michaelni@gmx.at>
