7d5732cb49 Remove dead code.
* libmisc/find_new_sub_gids.c: Remove dead code.
	find_new_sub_gids() is always called with *range_count set to 0.
	It's more difficult to keep the subordinate GIDs and UIDs
	synchronized, than for the user's UID/GId because the count of
	subordinate IDs may differ.

561ba96ec7 check for ruserok existence
rlogin support is old school code, so newer C libraries drop support for
ruserok (like uClibc, optionally).  But shadow doesn't build with that,
so have it check for ruserok to optionally enable rlogin.

c0ce911b5e userns: add argument sanity checking
In find_new_sub_{u,g}ids, check for min, count and max values.

In idmapping.c:get_map_ranges(), make sure that the value passed
in for ranges did not overflow.  Couldn't happen with the current
code, but this is a sanity check for any future potential mis-uses.
