diffutil: extract diff options code into a dedicated util-module
We want to be able to create and use diffoptions in more places. Currently the
official function to instantiate diffoptions live into `mercurial.patch`. A
module too high level to be easily imported in some places.
So we extract the diff options related function in their own utility module.
