scripts/get_maintainer.pl: Add --git-blame --rolestats "Authored lines" information

When options --git-blame and --rolestats are specified, add
the maintainers with the qualifying --git-min-percent amount
of lines authored of the complete file.  Does not add more
authors than specified by --git-max-maintainers.

For anyone using hg, this option works but is _very_ slow.
It's orders of magnitude slower than git slow.

The get_maintainer.pl version was incremented to 0.25.

This can be used with or without --git.

For instance:

$ ./scripts/get_maintainer.pl --git-blame --nogit --rolestats -f lib/bitmap.c
