Description

This is in path towards HBASE-13387
When the scan contains any filter, we have to call the filterRowKey(byte[],int,int) API. (Even if it is not interested in this method)
When the Cells coming in is offheap backed, we would need temp byte[] creation and copy row bytes to that. If we can make this Filter API to take a cell (which is the first cell in any row), we can avoid this overhead.
In 2.0.0 we will deprecate the old API with addition of new and FilterBase will give BC for old style custom Filters.
