6134d778d4 conf: Transport should be explictly configured in conf file
According to the currrent logic, it should be explictly defined
in the configuration file if the NVMe-oF target is started by
configuration file without using rpc calls. If no transport is
defined, we do not need to parse the following subsystems
but should terminate the NVMe-oF target .

2484d0d1cd bdev/nvme: write TransportID to config file
It was writing TransportId (lower-case d) instead.

While here, fix similar issue in etc/spdk/nvmf.conf.in.

lib/conf uses strcasecmp(), meaning TransportID and
TransportId are effectively the same, but it's better
to reduce confusion and just use the same in all places.

6bef902ca5 rpc: add default UNIX domain socket listen address
RPC is a default feature required for almost all usages,
so enable RPC by default, but with a UNIX domain socket
for security reasons.

-r can now be used from the command line to specify
an alternative RPC listen address from the default
/var/tmp/spdk.sock.

Remove the Enable parameter from the Rpc config section
but still allow specifying an alternative listen address
using the Listen parameter as an alternative to the
command line option.  This keeps backward compatibility
for this release for anyone using the configuration file
still.

Remove the Rpc sections from all configuration files
that were using them, except for those that specified
alternate TCP ports for multi-process test cases.  We
can fix these later to use an alternate UNIX domain
socket and to use the command line instead.

e5f6a99b61 nvmf: No longer use in capsule data buffers for CONNECT
Previously, the shared buffer pools were allocated on the
nvmf controllers. When a new connection was established,
the CONNECT command needs a 4k buffer, but we didn't know
which nvmf controller it belonged to until after the
CONNECT command completed. So there was a special case
for CONNECT that used in capsule data buffers instead.

Now, the buffer pool is global and always available. We
can just use that always, with no more special cases.

This has the additional nice side effect of allowing
users to run the target with no in capsule data buffers
allocated at all.

296add8bb1 nvmf: Add config options for inline and max I/O size
These don't actually work quite yet, but pipe the
configuration file data through to where it will
be needed.

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.

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.
