manifest: convert a recursive function to iterative one using stacks

I am debugging a memory issue from yesterday where `hg update` goes upto taking
22GB of memory on our internal treemanifest repository. This is an interesting
function and I saw memory consumption increasing while this function was
running.

It's sometimes hard to understand a recursive function and also the profile
won't show you actual operations which took time, rather it will show you the
function again and again in profile.

I am yet to notice any memory consumption decrease with this patch, but I
believe this will help like in making this a generator.
