Make SerializingCacheProvider the default if JNA is available
-------------------------------------------------------------

                 Key: CASSANDRA-3183
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-3183
             Project: Cassandra
          Issue Type: Task
          Components: Core
            Reporter: Jonathan Ellis
            Assignee: Jonathan Ellis
            Priority: Minor
             Fix For: 1.0.0


The serializing cache is a better choice for most users:

- Lower total memory usage (serialized data is usually 8x-12x smaller than "live" data in
the JVM with all the overhead that involves) means you can cache more rows for a given memory
footprint
- Moving the serialized rows off-heap means you can use smaller heaps, reducing the impact
of GC pauses
