96a54158bd nvmf: Assign each subsystem to an lcore
Each subsystem will run on a single core, which is more than enough
to fully saturate a device and a NIC. For now, all subsystems
run on the master lcore.

2653cb49a7 nvmf: define transport-specific address union
For now, it just contains RDMA, plus a raw byte array to allow generic
copying.

This never really made sense, so replace it with a list of
subsystems.

This is just extra complication for no real benefit.

fdc1278440 nvmf: simplify session and connection cleanup
The whole cleanup process is now started by
spdk_shutdown_nvmf_subsystems().  Each subsystem will clean up its
session, if any, and each session will clean up its connections.

1fc4a182bd nvmf: Subsystem now has a pointer to the session
There is only one controller per subsystem, so therefore
there can be 0 or 1 sessions. Change the list of sessions
to a pointer that can be NULL if no session exists.

f8296a99c2 nvmf: rename subsystem_grp.[ch] to subsystem.[ch]
NVMf does not have the concept of subsystem groups; the (former)
subsystem_grp files really contain structures and functions related to
individual subsystems.
