Apply SODA Nuriyuki's patch for multibyte support.
Based on soda-revised2.patch (in private mail) with a change from
soda on tech-userlevel.

Ok christos@.

Pass lint. From Anon Ymous

Address PR 30374 as suggested in there:

"Modify the man page to match the behaviour of "ls -q",

(done by yamt@ previously)

...
modify both the behaviour and documentation for "ls -b" and "ls -B" to
make spaces readily apparent. This could be done by adding VIS_WHITE
to the flags passed to strvis(3) in the safe_print() function in
src/bin/ls/util.c."

'ls -b' now yields foo\sbar (whitespace) foo\tbar (tab) foo\rbar (CR).
'ls -B' now yields foo\040bar foo\011bar foo\015bar.

- Add -h to usage.
- Use set/getprogname(3).

After last weeks addition of the '-b' flag, add '-B' and '-w' flags,
suggested by uwe@, inspired by FreeBSD. The three flags override
each other (and the '-q' flag) and behave as follows:

-B Force printing of non-printable characters in file names as
\xxx, where xxx is the numeric value of the character in octal.

-b As -B, but use C escape codes whenever possible.

-w Force raw printing of non-printable characters. This is the
default when output is not to a terminal.

Implement '-b' option, which, following FreeBSD, Linux and (I think) Solaris
prints octal escapes for nongraphic characters.

Sort options (AaBb...).

Move UCB-licensed code from 4-clause to 3-clause licence.

* implement -x; sort columns across the page rather than down the page
* in printcol(), don't bother building an index to the linked list if
only printing one column with printscol()...
* implement -n; prevent [gu]id->name mapping in long listings.
inspired by openbsd, but does *not* imply -l by itself.
* fix sorting with -d (or mismatched types in general). (from openbsd).
* document -g. (from openbsd).
