share and pc-sysinstall: adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Commit these apart because compile testing doesn't guarantee I didn't made
some nasty mistake. No functional change intended.

A few enhancements I made while working on the Firewire target (sbp_targ).

Update the error handling in a couple of cases to exit gracefully if
certain mandatory conditions aren't met.

Reduce the maximum number of initiators to 8 for this example code. While
1024 is more correct, this example code would act like it was stalled out
even though it was merely allocating the needed structures in init_ccbs()

Bump MAX_INITIATORS to 1024- the LSI-Logic can go even higher than
this for 'initiator id'- this is a stopgap until a sparse map is
added.

Make compat defines for offset format (FreeBSD 5 or less).

Add no-asyncio flag. There's some breakage with ASYNC I/O that every
now and then drops us into an infinite loop. This also then does
a fallback to no-asyncio if the AIO option isn't loaded/compiled into
the kernel.

A number of other chanes to try and track some breakage.

Bump the max number of initiators to 256 from 16. This is appropriate for
fibre channel and shouldn't hurt SPI.

- Enable 16byte commands.
- Fix printf warnings on 64bit architectures.
- Accept 'k', 'm' and etc. for -s option.

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.
