… in Python DataFrame. Python DataFrame.head/take now requires scanning all the partitions. This pull request changes them to delegate the actual implementation to Scala DataFrame (by calling DataFrame.take). This is more of a hack for fixing this issue in 1.5.1. A more proper fix is to change executeCollect and executeTake to return InternalRow rather than Row, and thus eliminate the extra round-trip conversion.

…array (round 2) This patch reverts most of the changes in a previous fix apache#8827. The real cause of the issue is that in `TungstenAggregate`'s prepare method we only reserve 1 page, but later when we switch to sort-based aggregation we try to acquire 1 page AND a pointer array. The longer-term fix should be to reserve also the pointer array, but for now ***we will simply not track the pointer array***. (Note that elsewhere we already don't track the pointer array, e.g. [here](https://github.com/apache/spark/blob/a18208047f06a4244703c17023bb20cbe1f59d73/sql/core/src/main/java/org/apache/spark/sql/execution/UnsafeKVExternalSorter.java#L88)) Note: This patch reuses the unit test added in apache#8827 so it doesn't show up in the diff.
