Now that rdma and tcp transports will be modularized,
we need to export a number of functions so they can call them.

Add a comment for what's going on. Remove negative logic.
I find this much easier to understand quickly, although
there are a few lines duplicated.

Protocol negotiation is logically a property of the
transports, so rds core need not set it.

Use kmem_cache_zalloc instead of kmem_cache_alloc/memset.

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.
