This one actually introduced by my last cleanup. (But helpfully pointed
out by the machines when I tried to upload my last cleanup to the AOSP
gerrit...)

mcookie simply prints out 16 bytes of entropy in hexadecimal; it is typically
used as the source for the "MIT magic cookies" that X11 uses for "secure"
connections.
The only implementation I know of is in util-linux; the problems with its
documented behavior motivated me to write an alternate implementation.
Specifically, getting 128 bytes from the kernel and finding the MD5 sum is
not a sane PRNG, especially when only 16 bytes are needed.

Inspired by some of the small patches that have gone by recently.
Limited to only things found in `generated/help.h`, plus a wider cleanup
for the more common "milisecond" typo.

reversed so the mask is 1<<(x&7) instead of 1<<(7-(x&7)). Can't _quite_
make printString() use unescape() out of lib because \q is a thing?

I don't know why NDK llvm is complaining about adjtime(), toys.h is #including
<sys/time.h> which http://man7.org/linux/man-pages/man3/adjtime.3.html says
is the right header...?

I accidentally added a tab in xargs.c, so as penance I'll clean up all
the tabs.

Not yet setting, no server/multicast, should validate source address...

Without this change, a successful modprobe on Android exits with status 1
because Android doesn't have /etc/modprobe.conf or /etc/modprobe.d/ ---
neither of which seem to be required on desktop Linux either.

If we do, we won't flush, and we might not output everything.
|
|
Otherwise in verbose mode we output bogus errors instead of `Success`.

From RFC 768, if UDP packet checksum computation yields a result of
zero, change it to hex 0xFFFF. The current udhcpc checksum verification
would yield false positive for this case. A better way is to compute the
checksum with the original checksum field and the result should be zero
for good udp packet.

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".

This is enough to cover the use cases of the Android users I know of.

* A number of logic and style fixes
* No longer changes toys.optargs and toys.optc
* Now supports ( ) ! -a -o
* Supports POSIX special cases for low argument count

modprobe was failing if you `modprobe a.ko`, then `modprobe b.ko` where b.ko
depends on a.ko --- b.ko will fail to load because a.ko is already loaded.
The code to handle this was incorrectly checking `rc` rather than `errno`
against EEXIST.
(We should pull the insmod.c equivalent of `ins_mod` out into lib/
and reuse it in modprobe.c, but I didn't want to get bogged down.)
