[SPARK-8464][Core][Shuffle][WIP] Consider separating aggregator and
non-aggregator paths in ExternalSorter
I've started by separating ExternalAggregator into two classes, one which
assumes an aggregator is defined and one which does not. There is a substantial
amount of code overlap so the next step is to extract common code into a parent
class.

extract out common code
