PartitionPruningRDD is using index from parent

I was getting a ArrayIndexOutOfBoundsException exception after doing union on pruned RDD. The index it was using on the partition was the index in the original RDD not the new pruned RDD.

TimeTrackingOutputStream should pass on calls to close() and flush().

Without this fix you get a huge number of open files when running shuffles.

AppendOnlyMap fixes

- Chose a more random reshuffling step for values returned by Object.hashCode to avoid some long chaining that was happening for consecutive integers (e.g. `sc.makeRDD(1 to 100000000, 100).map(t => (t, t)).reduceByKey(_ + _).count`)
- Some other small optimizations throughout (see commit comments)

Fix 'timeWriting' stat for shuffle files

Due to concurrent git branches, changes from shuffle file consolidation patch
caused the shuffle write timing patch to no longer actually measure the time,
since it requires time be measured after the stream has been closed.

Merge pull request #201 from rxin/mappartitions

Use the proper partition index in mapPartitionsWIthIndex

mapPartitionsWithIndex uses TaskContext.partitionId as the partition index. TaskContext.partitionId used to be identical to the partition index in a RDD. However, pull request #186 introduced a scenario (with partition pruning) that the two can be different. This pull request uses the right partition index in all mapPartitionsWithIndex related calls.

Also removed the extra MapPartitionsWIthContextRDD and put all the mapPartitions related functionality in MapPartitionsRDD.

Scheduler quits when newStage fails

The current scheduler thread does not handle exceptions from newStage stage while launching new jobs. The thread fails on any exception that gets triggered at that level, leaving the cluster hanging with no schduler.
