Includes initial test suite which runs correctly for com.bigdata.journal.
We still need a test for a concurrent writer while we are taking a snapshot.
I touched the proxy test suite a bit for the journal package. It was failing to call super.setUp() and super.tearDown(). I also had to change WORMStrategy.getProperties() to not set the CREATE_TEMP_FILE property once I made this change (the TestRWJournal suite already had this change).
Snapshot was not working (and was not tested) for WORMStrategy.
AbstractJournal.snapshotAllocationData() was calling ByteBuffer.array() even when the array was not visible. I have replaced this with BytesUtil.toArray(ByteBuffer).
writeOnStream() for the backing store now allows a null quorum (for non-HA invocations).
