Rehashes the contents of this map into a new array with a
larger capacity.  This method is called automatically when the
number of keys in this map reaches its threshold.

If current capacity is MAXIMUM_CAPACITY, this method does not
resize the map, but but sets threshold to Integer.MAX_VALUE.
This has the effect of preventing future calls.

@param newCapacity the new capacity, MUST be a power of two;
must be greater than current capacity unless current
capacity is MAXIMUM_CAPACITY (in which case value
is irrelevant).
