Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

Partial merge of the SPDX changes

These changes are incomplete but are making it difficult
to determine what other changes can/should be merged.

No objections from: pfg

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

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

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).

Fixes for ls(1) long format (-l) output:

- Allow -h option to work if the listing contains at least one device
file.
- Align major and minor device numbers correctly to the size field.

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).

Add missing options required by SUSv3:
-m List files across the page, separated by commas.
-p Print a slash after directory names
-x Same as -C but sort across the columns rather than down

WARNS=4 fixes, plus a healthy dose of fixes inspired by lint.

Add a new flag, -h which when combined with the -l option causes
file sizes to be displayed with unit suffixes; Byte, Kilobyte,
Megabyte, Gigabyte, Terabyte and Petabyte in order to reduce the
number of digits to three or less.

* 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. :-)

o Renamed '-b' (show unprintables in octal) to '-B'

o Added a new '-b' which behaves as in AT&T Unices (show unprintables in
octal, using C escape codes when possible)

o Added '?' to the getopt() string, since the code in the switch considers
it as a valid option.

Added -b option to display unprintables in octal.
