graphlog: refactor common grapher code

Extracts the column and edge determination code into a separate function
usable on generic DAGs with at most 2 parents per node.

grapher() is very similar to graphmod.graph(). I shall look into merging
them when I try visualizing patch branches in hgweb.

Started using contexts and renamed a bunch of variables (fewer underscores).

*** failed to import extension badext from .../badext.py: bit bucket overflow
