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.

6a1383813c nvmf: rename FabricIntf to Listen, add transport
Change the Port configuration file entries to a new format:

[Port1]
  Listen <transport> <address>:<service>

Initially, this still only supports RDMA, but the new format will allow
specifying other transports once they are added.

This is just extra complication for no real benefit.

a9df326a0e nvmf: only allow one Controller per Subsystem
Multiple NVMe controllers within a subsystem does not work correctly,
since we would need to virtualize the controller data, namespace IDs,
and so on.  For now, only allow pass-through mapping of a single NVMe
controller per subsystem.

196dfe4278 nvmf: remove MaxInCapsuleData configuration option
The maximum in-capsule data size is determined by the I/O queue bounce
buffer size, and there is no point in limiting it beyond that, so remove
the need to configure it.

42111e78de nvmf: replace IQN references with NQN
NVMe over Fabrics defines its own NVMe Qualified Name (NQN) format; it
does not use iSCSI Qualified Names.

Also change the default node base for nvmf_tgt to "nqn.2016-06.io.spdk".

This enables SPDK_NVMF_BUILD_ETC to be moved out of the library as well,

58f9dcd220 nvmf: Rename SubsystemGroup to Susbystem in conf file
The section is really defining a subsystem as defined
by the NVMf specification. There does not appear to be
any need for a group of subsystems.

This change only updates the configuration file. It does
not remove all references to a subsystem group from
the code.

a4b857213b nvmf: Rename InitiatorGroup config section to Host
The specification refers to this concept as a Host,
so use that term. This only changes the configuration
file usage. Initiator groups are still referenced in
the code and will be removed later.
