SPARK-1145: Memory mapping with many small blocks can cause JVM allocation
failures
This includes some minor code clean-up as well. The main change is that
small files are not memory mapped. There is a nicer way to write that code
block using Scala's `Try` but to make it easy to back port and as simple as
possible, I opted for the more explicit but less pretty format.
