Subject: [PATCH] get_maintainer.pl: Add optional .get_maintainer.MAINTAINERS override

OSes have additional maintainers that should be cc'd on patches or may
want to circulate internal patches.

Parse the .get_maintainer.MAINTAINERS file.  Entries in the file
can begin with a '+' to indicate the email and list entries should be
added to the exiting MAINTAINERS output, or a '-' to indicate that the
entries should override the existing MAINTAINERS file.

Also add a help entry for the .get_maintainers.ignore file.
