I converted allprison_mtx mutex to allprison_lock sx lock. To fix this LOR,
move prison removal to prison_complete() entirely. To ensure that noone
will reference this prison before it's beeing removed from the list skip
prisons with 'pr_ref == 0' in prison_find() and assert that pr_ref has to
greater than 0 in prison_hold().

This hopefully fixes problems that people running with SYMVER_ENABLED
are experiencing.
Linux SCSI SG passthrough device API. The intention is to allow for both
running of Linux apps that want to talk to /dev/sg* nodes, and to facilitate
porting of apps from Linux to FreeBSD. As such, both native and linuxolator
entry points and definitions are provided.
Caveats:
- This does not support the procfs and sysfs nodes that the Linux SG
driver provides. Some Linux apps may rely on these for operation,
others may only use them for informational purposes.
- More ioctls need to be implemented.
- Linux uses a naming scheme of "sg[a-z]" for devices, while FreeBSD uses a
scheme of "sg[0-9]". Devfs aliasis (symlinks) are automatically created
to link the two together. However, tools like camcontrol only see the
native names.
- Some operations were originally designed to return byte counts or other
data directly as the syscall return value. The linuxolator doesn't appear
to support this well, so this driver just punts for these cases.
Now that the driver is in place, others are welcome to add missing
functionality. Thanks to Roman Divacky for pushing this work along.

- Added magic numbers to pretend the NEC original program version

installaer of the IPLware put 'call $0x09ab' instruction.
- Put the near return instruction at 0x9ab in selector.s.
