MFC r287621: Reimplement CTL High Availability.
CTL HA functionality was originally implemented by Copan many years ago, but large part of the sources was never published. This change includes clean room implementation of the missing code and fixes for many bugs.
This code supports dual-node HA with ALUA in four modes: - Active/Unavailable without interlink between nodes; - Active/Standby with second node handling only basic LUN discovery and reservation, synchronizing with the first node through the interlink; - Active/Active with both nodes processing commands and accessing the backing storage, synchronizing with the first node through the interlink; - Active/Active with second node working as proxy, transfering all commands to the first node for execution through the interlink.
Unlike original Copan's implementation, depending on specific hardware, this code uses simple custom TCP-based protocol for interlink. It has no authentication, so it should never be enabled on public interfaces.
The code may still need some polishing, but generally it is functional.

MFC r286807: Move "ioctl" CAM frontend into separate file.
It has nothing to share with too huge ctl.c other then device descriptor, but even that may be counted as design error that may be fixed later. At some point we may even want to have several ioctl ports.

MFC r286806: Drop "internal" CTL frontend.
Its idea was to be a simple initiator and execute several commands from kernel level, but FreeBSD never had consumer for that functionality, while its implementation polluted many unrelated places.

MFC r268767: Add support for VMWare dialect of EXTENDED COPY command, aka VAAI Clone.
This allows to clone VMs and move them between LUNs inside one storage host without generating extra network traffic to the initiator and back, and without being limited by network bandwidth.
LUNs participating in copy operation should have UNIQUE NAA or EUI IDs set. For LUNs without these IDs VMWare will use traditional copy operations.
Beware: the above LUN IDs explicitly set to values non-unique from the VM cluster point of view may cause data corruption if wrong LUN is addressed!

Remove ctl(4) from GENERIC. Also remove 'options CTL_DISABLE' and kern.cam.ctl.disable tunable; those were introduced as a workaround to make it possible to boot GENERIC on low memory machines.
With ctl(4) being built as a module and automatically loaded by ctladm(8), this makes CTL work out of the box.
