c38b150ae4 New SCSI target emulator code
This code allows a user program to enable target mode on a SIM and
then emulate any number of devices (disks, tape drives, etc.)  All
decisions about device behavior (UA, CA, inquiry response) are left
to the usermode program and the kernel driver is merely a conduit
for CCBs.  This enables multiple concurrent target emulators, each
using its own backing store and IO model.

Also included is a user program that emulates a disk (RBC) using a
file as a backing store.  This provides functionality similar to
md(4) at the CAM layer.

Code has been tested on ahc(4) and should also work on isp(4) (and
other SIMs that gain target mode support).  It is a complete rewrite
of /sys/cam/scsi_target* and /usr/share/examples/scsi_target.

4535126875 Turn on unconditional symbol export for modules whose API is
not clear enough, will require additional analysis, or will
require some input from their maintainers.

74bd1c1038 CAM, the module: scbus, da, cd, and st wrapped in one module.
Make the umass driver depend on this module.

Makes it possible to compile the kernel without SCSI support and load it
when for example a USB floppy is conencted.
