useradd/groupadd are provided by shadow in Linux:
	http://pkg-shadow.alioth.debian.org/
	https://github.com/shadow-maint/shadow.git

behavior of other Unixes isn't important in this regard i don't think.
if you want to see the mess, just look at the cruft we have in Gentoo:
	https://gitweb.gentoo.org/repo/gentoo.git/tree/eclass/user.eclass
we don't want that in busybox.

adduser/addgroup tend to be symlinks or wrappers, if they exist at all,
but by and large are deprecated.  busybox should implement applets that
mimic shadow here and deprecate the old ones, if not throw them out.
although we can probably rename & massage the sources in these cases.

patches welcome ;)
