This only touches 24 of the 68 toys/posix/ files --- the others were
already canonical.
Potentially contentious, so worth stating explicitly, is that there
were 8 matches for "COMMAND..." amongst all existing help output,
with 7 matches for various inconsistent variants involving something
with "ARG", so I resolved that in favor of using "COMMAND..." (which
is also shorter overall, and avoids nested []s).

This doesn't (yet) add shell builtin awareness to time, kill, or pwd,
just lets them run in the shell process.
|
|
Otherwise kill flags don't work unless killall5 is also configured.
Also switch to the FLAG() macro.

Include all the signals, not just the POSIX ones.
In particular, improve support for real-time signals. My attempt to
switch AOSP builds over to toybox timeout got reverted when I broke the
ART build bots which use SIGRTMIN+2.
Also fix `kill -l 3` to show "QUIT" and `kill -l QUIT` to show "3".
Also make the `kill -l` output include numbers and names, and format it
to look better on a 80x24 tty, because it's always August 1978 somewhere.

Be consistent about upper versus lower case. (Upper seems to have the
majority, so I went with that, though I'm happy to provide the opposite
patch as long as we're consistent!)
Be consistent about using \t. (Though saving a few bytes seems like it
might be better done in the code that generates help.h rather than
directly in the source, since tabs make careful ASCII art layout hard
enough that we regularly have things misaligned.)
Remove trailing periods (most of which seem to have been added by me).
Always use the US "human readable" rather than my British
"human-readable", and be more consistent about declaring whether we're
showing multiples of 1000 or 1024.
Just say "verbose" rather than adding a useless "mode" or "output".

From eyeballing the output of
for i in `./toybox | tr " " "\n"` ; do ./toybox $i --help ; done | \
grep '^-' | grep -v "\t"

Slight conflict here: this puts killall5 in the posix directory. But the commands sharing code trumps that.
|

other places that were setting it that no longer need to.

right in years (ubuntu broke its' vim implementation). Remove trailing spaces. Add/remove blank lines. Re-wordwrap in places. Update documentation with new coding style.
The actual code should be the same afterward, this is just cosmetic refactoring.

FOR_commandname before #including toys.h to trigger it. Rename DEFINE_GLOBALS() to just GLOBALS() (because I could never remember if it was DECLARE_GLOBALS). Convert existing commands to use new infrastructure, and replace optflag constants with FLAG_ macros where appropriate.
