97c31821eb ls(1): Allow LSCOLORS to specify an underline
Allows capitalizing the background color character to enable an
underline instead of bold, capitalizing the foreground color char will
still do bold.

e10ba80063 ls(1): Add --color=when
--color may be set to one of: 'auto', 'always', and 'never'.

'auto' is the default behavior- output colors only if -G or COLORTERM are
set, and only if stdout is a tty.

'always' is a new behavior- output colors always. termcap(5) will be
consulted unless TERM is unset or not a recognized terminal, in which case
ls(1) will fall back to explicitly outputting ANSI escape sequences.

'never' to turn off any environment variable and -G usage.

0fdf7fa846 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).

8a16b7a18f 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.

fbbd9655e5 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.

71b8b74887 Add the -S option to sort files by size. NetBSD and OpenBSD already
have this option with identical semantics (sorting large files first).
-r can be used to reverse the sort if that is desired.

107409f46e Treat filenames as multibyte character strings (according to the current
LC_CTYPE setting) when determining which characters are printable.
This is an often-requested feature.

Use wcwidth() to determine the number of column positions a character
takes up, although there are still a few places left where we assume
1 byte = 1 column position, e.g. line-wrapping when handling the -m option.

The error handling here is somewhat more complicated than usual: we do
our best to show what we can of a filename in the presence of conversion
errors, instead of simply aborting.

c1499cf6cf Revamp the colour support to allow for bold characters. Colours
are now defined using the characters a-h and A-H for the bold
variants.  The old way using 0-7 for the colours still works, but
prints a message asking the user to switch.

5a890e22bf Don't look up the ANSI sequences each time a colour is changed,
this is extremely inefficient, instead write them all down at the
beginning.

The correct sequence to switch colours off is to first use 'op' if
it exists, otherwise use 'oc'.  If neither of these exist then we
shouldn't be doing colour with this terminal.

74985094ef * 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.

3885812c8c 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.
