The Spliterators returned by values, entrySet, and keySet incorrectly
reported the SIZED characteristic, instead of CONCURRENT. This could
lead to bugs when the map is concurrently modified during a stream
operation.

For keySet and values, the incorrect characteristics are inherited from
AbstractMap, so to rectify that the respective methods are overridden,
and custom collections are provided that report the correct Spliterator
characteristics.
