[WIP]Combine splits by size
The idea is simple and it try to solve this problem by combining splits by
size which has been generated by the underlying inputformat, so it would
support all of the inputformat in theory.
The combining size can be specified by `spark.sql.mapper.splitCombineSize`,
the default value is: -1 meaning turn off the combining logic.
i.e partition -> splits-> [combineSplit, combineSplit,...]-> RDD
