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.

Previously, we used cap_lo and cap_hi to represent the 32-bit halves of
the full CAP register. However, it is simpler to keep them in a single
64-bit structure, and is no less efficient on 64-bit platforms.
Also name the NSSRS field from NVMe 1.2, which was previously reserved.

This will allow removal notifications to be propagated to the library
user (e.g. for hotplug).
The callback is currently unused, but this at least prepares the API for
the future hotplug support.

vtophys() was checking for out-of-range addresses incorrectly: vfn_2mb
is already shifted to account for 2 MB hugepages, but it was being
compared with a mask that did not account for the shift. This would
allow out-of-bounds access to the 128tb map array for certain invalid
addresses (it had no effect on addresses within the valid userspace
range).

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

When recursively calling spdk_json_write_val() on another object or
array, the child call will handle printing out the whole
subobject/array, so the parent call should skip over all of its values.
Also fix the return value for the array/object case - if we get to the
end of the array or object, we should return 0 for success.
