89031c3e27 nvmf: move discovery subsystem creation to conf.c
It is not currently configurable, but this will allow us to make the
discovery subsystem have config options (e.g. which lcore to run on).

944695ca21 nvmf: Remove controller.[ch] and probe for each subsystem.
This is a much simpler approach and is only slightly
less efficient.

2b9d85c448 nvmf: Remove host.[ch] and port.[ch]
These can be simplified and merged into the subsystem.

Remove the concept of mappings from subsystems and replace
it with a list of hosts and ports. The host is optional -
not specifying a host means any host can connect.

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.

32a70c1ffc nvmf: Remove subsystem groups
This never really made sense, so replace it with a list of
subsystems.

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.
