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.)

The problem with testing changes on my desktop is that they won't always
compile when I try to sync AOSP...

(My apologies for mixing these two unrelated changes up.)

Inline #define bcg TT (from generated/globals.h)
Inline BC_FLAG with FLAG_ values from generated/flags.h.
Replace BC_MAX() and BC_MIN() with maxof() and minof() from
Inline BC_INVALID_IDX (it's used twice and doesn't need a typecast).
Inline bc_func_insertParam() and bc_func_insertAuto() (each is used once).

Implement -c, fix endless loop when illegal char happens with
!outleft (don't need to check errno, just in == toybuf), refill
buffer each time (less efficient handling of illegal chars but never
have to worry about how long constitutes a valid sequence in unknown
encoding).
Fix input longer than 2k (memmove() has src/dest switched, second time through
loop in starts at offset inleft...) Made it start at beginning every time.
Switch iconv_open() error msg to show to/from and errno (rather than
hardwired english text).
