graphmod: add a function for topological iteration
This changeset introduces a function to perform topological (one branch after
the other) iteration over a set of changesets. This first version has a lot of
limitations, but the approach should be flexible enough to allow many
improvements in the future. This changeset aims to set the first stone more
than providing a complete solution.
The algorithm does not need to know the whole set of nodes involved
before emitting revision. This makes it a good candidate for usage in place
like `hg log` or graphical tools that need a fast first result time.
