Remove $FreeBSD$: one-line .c pattern

Remove /^[\s*]*__FBSDID\("\$FreeBSD\$"\);?\s*\n/

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.

CID: 1210464, 1006640, 1006868, 1007292, 1009091, 1009822, 1009824

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.

Fxi a bunch of typos.

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.

Remove unnecessary pccard/cardinfo.h include.

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.

make this warns=5 clean

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