[PATCH 1/6] get_maintainer.pl: Add .get_maintainer.ignore file capability

[Joe Perches]

Some people prefer not to be cc'd on patches.
Add an ability to have a file (.get_maintainer.ignore) with
names and email addresses that are excluded from being listed
except when specifically listed as a maintainer in a section.
