userns: Allow any uid or gid mappings that don't overlap.
When I initially wrote the code for /proc/<pid>/uid_map. I was lazy and avoided duplicate mappings by the simple expedient of ensuring the first number in a new extent was greater than any number in the previous extent. Unfortunately that precludes a number of valid mappings, and someone noticed and complained. So use a simple check to ensure that ranges in the mapping extents don't overlap.
