util/lint: Update tools that use git to use a library

Browse Source 
Each of the tools that used git had similar functionality. This combines
all of that into a single script that gets sourced by each.  This makes
maintenance much easier.

By doing this and updating each of the scripts to do the correct thing
if the script isn't being run in a git repository, it makes them work
much better for the releases, which are just released as a tarball,
without any attached git repository.
