Josh Rosen 33cd3a0c12 Remove map-side combining from ShuffleMapTask. 
This separation of concerns simplifies the 
ShuffleDependency and ShuffledRDD interfaces.

Map-side combining can be performed in a
mapPartitions() call prior to shuffling the RDD.

I don't anticipate this having much of a 
performance impact: in both approaches, each tuple
is hashed twice: once in the bucket partitioning
and once in the combiner's hashtable.  The same
steps are being performed, but in a different
order and through one extra Iterator.

Josh Rosen 10bcd217d2 Remove mapSideCombine field from Aggregator. 
Instead, the presence or absense of a ShuffleDependency's aggregator
will control whether map-side combining is performed.

Matei Zaharia dc28a3ac0a Modified shuffle to limit the maximum outstanding data size in bytes, 
instead of the maximum number of outstanding fetches. This should make
it faster when there are many small map output files, as well as more
robust to overallocating memory on large map outputs.

Matei Zaharia 6098f7e87a Fixed cache replacement behavior of BlockManager: 
- Partitions that get dropped to disk will now be loaded back into RAM
  after they're accessed again
- Same-RDD rule for cache replacement is now implemented (don't drop
  partitions from an RDD to make room for other partitions from itself)
- Items stored as MEMORY_AND_DISK go into memory only first, instead of
  being eagerly written out to disk
- MemoryStore.ensureFreeSpace is called within a lock on the writer
  thread to prevent race conditions (this can still be optimized to
  allow multiple concurrent calls to it but it's a start)
- MemoryStore does not accept blocks larger than its limit

Matei Zaharia 83143f9a5f Fixed several bugs that caused weird behavior with files in spark-shell: 
- SizeEstimator was following through a ClassLoader field of Hadoop
  JobConfs, which referenced the whole interpreter, Scala compiler, etc.
  Chaos ensued, giving an estimated size in the tens of gigabytes.
- Broadcast variables in local mode were only stored as MEMORY_ONLY and
  never made accessible over a server, so they fell out of the cache when
  they were deemed too large and couldn't be reloaded.
