Do not launch JavaGateways on workers (SPARK-674).
...
The problem was that the gateway was being initialized whenever the
pyspark.context module was loaded. The fix uses lazy initialization
that occurs only when SparkContext instances are actually constructed.
I also made the gateway and jvm variables private.
This change results in ~3-4x performance improvement when running the
PySpark unit tests.

Fix PythonPartitioner equality; see SPARK-654.
...
PythonPartitioner did not take the Python-side partitioning function
into account when checking for equality, which might cause problems
in the future.
