I'll make similar changes to more modules under ext/ and add them to this PR. That will hopefully make reviewing more straightforward.

I resolved conflicts on this.

@richardleach, if you wish to pursue this pull request further, could you resolve merge conflicts and re-push? Thanks.

@richardleach, because this (draft) p.r. touches many different files, it's going to be prone to merge conflicts. Should you wish to pursue it, could you resolve the current merge conflict(s) and reply to @Leont's question above? Thanks.

I'll get this done by early in Jan. Thanks.

This has been rebased and Leon's macro suggestion implemented. Does anyone want to give this another once over before it gets merged?

newAV_mortal() needs docs. "make test" currently outputs to stderr: no docs for newAV_mortal

Thanks for the spot. I'll write something this week.
