flagutil: create a `mercurial.revlogutils.flagutil` module

The flagprocessings logic is duplicated in 2 extra places, and usually in a less
robust flavor. This is a maintenance nightmare that I would like to see cleaned
up. To do so I am creating a `flagutil` module to move flag processings related
code and make it easily reusable by other code.
