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.

# Path to repo or hgweb config to serve (see 'hg help hgweb')
config = "/path/to/repo/or/config"

# Uncomment and adjust if Mercurial is not installed system-wide
# (consult "installed modules" path from 'hg debuginstall'):
#import sys; sys.path.insert(0, "/path/to/python/lib")

# Uncomment to send python tracebacks to the browser if an error occurs:
#import cgitb; cgitb.enable()
