Closes a window where address resolution can attach an rdma_cm_id to a
device during destruction of the rdma_cm_id. This can result in the
rdma_cm_id remaining in the device list after its memory has been
freed.

Modifications to the existing rdma header files, core files, drivers,
and ulp files to support iWARP, including:
- Hook iWARP CM into the build system and use it in rdma_cm.
- Convert enum ib_node_type to enum rdma_node_type, which includes
the possibility of RDMA_NODE_RNIC, and update everything for this.

3 seems like a low number of IB Communication Manager retries to set;
we see connections failing under stress, and in any case 3 just looks
like an arbitrary number. 15 is the max value allowed by the
InfiniBand spec.

The device address contains unsigned character arrays, which contain raw GID
addresses. The GIDs may not be naturally aligned, so do not cast them to
structures or unions.

This was spotted by coverity #id 1300. Since the array has only four
elements, we should just use those four.

Kernel connection management agent over InfiniBand that connects based
on IP addresses. The agent defines a generic RDMA connection
abstraction to support clients wanting to connect over different RDMA
devices.
The agent also handles RDMA device hotplug events on behalf of clients.
