This series adds support for mapping ranges of user/group IDs using the
newuidmap and newgidmap programs from shadow. The intent is to allow
for root-less bootstrapping of Linux root filesystems with correct
ownership. My primary inspiration is mmdebstrap [1], which uses
unshare(2) to create Debian root filesystems without needing root
access.
