JAVA-1005, JAVA-1003, JAVA-1007, JAVA-1009: Ported PooledConnectionProvider from 3.0.x, and refactored DBPort to work with it by extracting a Connection interface that it implements.  This new connection pool is non-blocking, and supports enforcement of max idle time, max life time, and minimum size.  It also abstracts the JMX monitoring into an implementation of the ConnectionPoolListener interface, which the connection pool fires events to.
