Fix typo & build

Add a number of sanity checks to the data that we're handling from the
CIS. Coverity has tagged it as tainted. While this data is more
trusted than your average data, we still need to do some basic
validation on it. Check ioctl return value to ensure we switch memory
targets between common and attribute as well as the lseek.

various: general 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.

No functional change intended.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

Move sys/pccard/*.h here.

Fix check for link target so we don't print cardbus CIS information twice.
Also, eliminate some magic constants and replace them with values from cis.h.

Restore now-useless ioctl as a roadmap. The original dumpcis code
assumed it had to toggle between attribute and common memory in the
cards. The kernel is supposed to cope with that automatically and
give us a tuple list. However, there's a number of details of how
that happens that's currently, ummm, magical and/or not implemented
for 16-bit PC Cards that have CIS_LONGLINK_C tuples in them (eg, mix
both attribute memory and common memory). Also, CIS_LOGNLINK_A
entries might not be handled completely correctly either, since there
can be gaps in the attribute vs common stuff.

All this will need to be corrected in the kernel. Once it is
corrected, dumpcis can be made even simpler in some ways, a little
more complicated in others once an API for presentation of CIS to
userland in these weird cases is settled upon.

More dead code removal.

The original programs that this code was lifted from (pccardd and
pccardc) parsed data to make decisions about stuff related to card
configuration.

The purely CIS dumping aspect of this program obviates the need for
such parsing. Save some space and don't parse the data anymore for
configuration purposes. Just parse it to print an interpreatation of
it.

dump() really is unused, so retire it.

make this warns=5 clean

Move dumpcis to its own directory, start to decouple from the
pccardc/pccardd history.
