bin: Remove ancient SCCS tags.

Remove ancient SCCS tags from the tree, automated scripting, with two
minor fixup to keep things compiling. All the common forms in the tree
were removed with a perl script.

ls: Improve POSIX compatibility for -g and -n.

- Change -g (ignored for BSD 4.3 compatibility since BSD 4.4)
to use POSIX semantics of implying -l but omitting the owner's
name.

- Change -n to imply -l.

The -o option remains unchanged (POSIX defines -o as a complement to
-g that implies -l but omits group names whereas BSD defines -o to add
file flags to -l). This compromise is the same used by both NetBSD
and OpenBSD.

Convert ls(1) to not use libxo(3)

libxo imposes a large burden on system utilities. In the case of ls, that
burden is difficult to justify -- any language that can interact with json
output can use readdir(3) and stat(2).

Logically, this reverts r291607, r285857, r285803, r285734, r285425,
r284494, r284489, r284252, and r284198.

Kyua tests continue to pass (libxo integration was entirely untested).

General further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 3-Clause license.

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.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

Fix some issues with the application of libxo to ls(1)

* Add whitespace trimming to some fields (username, group, size, inode, blocks) to avoid whitespace in JSON strings
* fix -m mode, was invalid JSON (repeated keys), and was missing outer array container
* in -n mode, numeric uids and gids were returned as strings

Replace spaces with tabs where appropriate.

Add y flag and environment variable LS_SAMESORT to specify the same
sorting order for time and name with the -t option. IEEE Std 1003.2
(POSIX.2) mandates that the -t option sort in descending order, and
that if two files have the same timestamp, they should be sorted in
ascending order of their names. The -r flag reverses both of these
sort orders, so they're never the same. This creates significant
problems for sequentially named files stored on FAT file systems,
where it can be impossible to list them in the order in which they
were created.

Add , (comma) option to print file sizes grouped and separated by
thousands using the non-monetary separator returned by localeconv(3),
typically a comma or period.

Get rid of major/minor number distinction.

As of FreeBSD 6, devices can only be opened through devfs. These device
nodes don't have major and minor numbers anymore. The st_rdev field in
struct stat is simply based a copy of st_ino.

Simply display device numbers as hexadecimal, using "%#jx". This is
allowed by POSIX, since it explicitly states things like the following
(example taken from ls(1)):

"If the file is a character special or block special file, the
size of the file may be replaced with implementation-defined
information associated with the device in question."

This makes the output of these commands more compact. For example, ls(1)
now uses approximately four columns less. While there, simplify the
column length calculation from ls(1) by calling snprintf() with a NULL
buffer.

Don't be afraid; if needed one can still obtain individual major/minor
numbers using stat(1).

A new jail(8) with a configuration file, to replace the work currently done

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.

Teach "ls -Z" to use the policy-agnostic MAC label interfaces rather
than the LOMAC-specific interfaces for listing MAC labels. This permits
ls to view MAC labels in a manner similar to getfmac, when ls is used
with the -l argument. Next generation LOMAC will use the MAC Framework
so should "just" work with this and other policies. Not the prettiest
code in the world, but then, neither is ls(1).

* Re-implement colour support using termcap's AF and AB capabilities
to manage the ANSI colour sequences. Colour support is disabled
unless the TERM environment variable references a valid termcap.

* Allow optional compilation of the colour support in the Makefile,
defaulting to yes. This allows us to switch it off for fixit
floppies and other mediums where space is an issue and the extra
bloat of statically linking with ncurses isn't acceptable.

* Display a warning if colour is requested with '-G' but support
for it isn't compiled in.

Add colour support to /bin/ls (at a cost of 1056 bytes on my system).

It is not switched on by default and must be enabled with the -G
flag. When using ls -G the output behaviour is modified with ANSI
colour sequences wrapped around filenames to help distinguish file
types. (Colours can be redefined in the LSCOLORS environment
variable as described in the manual page.)

Colour support is silently disabled (if switched on) if stdout
isn't a tty.

Allow env. variable LS_COLWIDTHS to specify minimum column widths,
effectively overriding the dynamically-sized-column feature. This
is mostly useful for non-interactive use, where it may be necessary
to ensure that listings taken at different times have columns that
line-up correctly. I have been assured that at least one large,
well-known program will soon be taking advantage of this. :-)
