An in-kernel C pointer, to a SCSI target device, is
not sufficient in all cases to address a target. This plays out most
often in userland interfaces such as ioctls.
The C pointer is all the interface between core and low-level needs.
All other means of addressing (IDs, labels, ... of which HCIL is only
one kind) are only meaningful to userspace. The labels may be
_generated_ at any level (low, core, high) depending on their context,
but they are _used_ only in userspace->kernel interfaces.
The core provides the map of devices<->labels.
