If you want to change the existing macro, then you have to rename it,
because it no longer does goto...
Also I kind of disagree with Nicholas that we should always assign a ret
variable, I think a single error statement is better. For example in the
case above a goto fail is a lot nicer (and returning ENOMEM) there.
Please wait a bit before a conclusion is reached about the macro,
and only implement it later.
Also this patch is non-trivial now, and some changes are definitely not OK
(e.g removing ff_h264_free_tables(h) and similar cleanup functions from
the failure path).
