Suggesting mode 2770 is dangerous because it makes the binary writeable
by all members of the owning group which is supposed to be normal
end-users. Suggest 2710 instead as is usual for s[ug]id binaries,
allowing execution but neither reading nor writing.

As the large uids are usually provided by remote user identity and
authentication service, which also provide user login tracking,
there is no need to create a huge sparse file for them on every local
machine.
fixup! login.defs: Add LASTLOG_UID_MAX variable to limit lastlog to small uids.
Should have been: '[...] but only checkS [...]'.
So there was a missing 's'. Architectures isn't the right word either.
I decided to write the whole sentence new.
This functionality is useful because there is now a feature
of Linux-PAM's pam_lastlog module to block expired users (users
which did not login recently enough) from login. This commit
complements it so the sysadmin is able to unblock such expired user.

When referring to USERGROUPS_ENAB, the German mentions /etc/default/useradd
when it should be /etc/login.defs (like the original English does).

Until now only exact username specification in /etc/sub[ug]id file allowed the
mapping. This prevented normal use for those users who use multiple usernames
with the same UID, as it rejected mapping even though it was allowed for
another username with the same UID.
This patch initially retains the old behaviour, for performance's sake. In the
first pass, new[ug]idmap only searches for exact username match.
If that yields no valid results, it continues into another loop, which does UID
resolution and comparison. If either definition (numeric UID mapping
specification or mapping specification for another username with the same UID as
current username) is found, it is used.

Users may otherwise be confused and think that because the kernel
does not restrict uid mappings to the root user (within his
current uid mappings), newuidmap will ignore /etc/subuid for the
root user. It will not.
