This fixes error handling for BeOS, removing the need for some ifdefs.
...
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.

I still don't think this should be here. Note: without this code DV encoder
...
will accept incorrect pix_fmt's and such, but decoder will work much better
with containers not setting the same attributes. It seems like there will
be a generic mechanism for checking such constraints, but if not I can always
resurrect this check for *encoder* only.

size[0-3] are not initialized (and can get random negative trash
...
values), so the comparison with vs_total_ac_bits is messed up on the
first couple loop iterations, leading to AC underflows.
the b->prev[] pointers were not being maintained correctly. We
potentially have to update b->prev[] both before and after the area
whose VLC length is getting adjusted.
this also might fix the ppc regression failure?
