AVERROR_ defines are moved to avcodec.h as they are needed in there as well. Feel free to move that to avutil/common.h.
Bumped up avcodec/format version numbers as though it's binary compatible we will want to rebuild apps as error values changed.
Please from now on use return AVERROR(EFOO) instead of the ugly return -EFOO in your code.
This also removes the need for berrno.h.

there is a very small chance that a stream which is damaged && unseekable && very small packet && damage to the flags && unlucky buffer state could have a valid packet after a damaged packet lost, but i think this is so unlikely that the simplification outweights it
mans if you disagree with any commit to mpeg.c just say so and ill revert it
