scripts/get_maintainer.pl: use mailmap in name deduplication and other updates
Use Florian Mickler's mailmap routine to reduce name duplication. o Add subroutine deduplicate_email to centralize code o Add hashes for deduplicate_(name|address)_hash o Remove now unused @interactive_to o Whitespace neatening o Add command line --help text o Add --mailmap command line option control o Interactive changes: - Add toggles for maintainer, git and list selections - Default selection is all - Add mailmap control Update to 0.26-beta5 Signed-off-by: Joe Perches <joe@perches.com> Cc: Florian Mickler <florian@mickler.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
