      Description

      We need to document the new off-heap memory limit configurations which were added in Spark 1.6, add simple configuration validation (for instance, you shouldn't be able to enable off-heap execution when the off-heap memory limit is zero), and alias the old and confusing `spark.unsafe.offHeap` configuration to something that lives in the `spark.memory` namespace.
