00e0f34c61 RDS: Connection handling
While arguably the fact that the underlying transport needs a
connection to convey RDS's datagrame reliably is not important
to rds proper, the transports implemented so far (IB and TCP)
have both been connection-oriented, and so the connection
state machine-related code is in the common rds code.

This patch also includes several work items, to handle connecting,
sending, receiving, and shutdown.

a8c879a7ee RDS: Info and stats
RDS currently generates a lot of stats that are accessible via
the rds-info utility. This code implements the support for this.

0fbc78cbf5 RDS: Transport code
RDS supports multiple transports. While this initial submission
only supports Infiniband transport, this abstraction allows others
to be added. We're working on an iWARP transport, and also see
UDP over DCB as another possibility.

This code handles transport registration.

922cb17a5c RDS: Congestion-handling code
RDS handles per-socket congestion by updating peers with a complete
congestion map (8KB). This code keeps track of these maps for itself
and ones received from peers.
