Drop "internal" CTL frontend.

Browse Source 
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..

@ -366,16 +366,6 @@ This is a CTL frontend port that is also a CAM SIM. The idea is that this
frontend allows for using CTL without any target-capable hardware. So any
LUNs you create in CTL are visible via this port.

ctl_frontend_internal.h:
-----------------------
This is a frontend port written for Copan to do some system-specific tasks
that required sending commands into CTL from inside the kernel. This isn't
entirely relevant to FreeBSD in general, but can perhaps be repurposed or
removed later.

.It Ic bbrread
Issue a SCSI READ command to the logical device to potentially force a bad
block on a disk in the RAID set to be reconstructed from the other disks in
the array. This command should only be used on an array that is in the
normal state. If used on a critical array, it could cause the array to go
offline if the bad block to be remapped is on one of the disks that is
still active in the array.
.Pp
The data for this particular command will be discarded, and not returned to
the user.
.Pp
In order to determine which LUN to read from, the user should first
determine which LUN the disk with a bad block belongs to. Then he should
map the bad disk block back to the logical block address for the array in
order to determine which LBA to pass in to the
.Ic bbrread
command.
.Pp
This command is primarily intended for testing. In practice, bad block
remapping will generally be triggered by the in-kernel Disk Aerobics and
Disk Scrubbing code.
