Allow a user to control some of the RDMA related attributes
of an rsocket through setsockopt/getsockopt. A user specifies
that the rsocket should be modified through SOL_RDMA level.
This patch provides the initial framework. Subsequent patches
will add the configurable parameters.

This deviates from standard sockets, but it seems to be the best way
to provide the user some control over the RDMA portion of an rsocket.
