i2c-tools: don't include linux/i2c-dev.h
Installing headers from upstream i2c-tools makes it impossible to
build the busybox version due to redefined symbols. This is caused by
the fact that linux/i2c-dev.h from i2c-tools overwrites the one from
linux uapi and defines symbols already defined by linux' linux/i2c.h.
Drop this include and simply re-implement the relevant defines from
linux/i2c-dev.h in miscutils/i2c-tools.c.

kill: add '--' option to separate options from arguments
Using a negative pid to send TERM to a process group results in an
obscure error:

This is intended. Manpage says:
ARGUMENTS
pid Each pid can be one of four things:
...
-n where n is larger than 1. All processes in process group
n are signaled. When an argument of the form '-n' is
given, and it is meant to denote a process group, either
a signal must be specified first, or the argument must be
preceded by a '--' option, otherwise it will be taken as
the signal to send.

klibc-utils: new applets: resume, nuke, minips
minips is a pure alias to ps, just in case someone needs 100% klibc-utils compat.

[PARSER] Catch variable length expansions on non-existant specials
Currently we only check special variable names that follow directly
after $ or ${. So errors such as ${#&} are not caught. This patch
fixes that by moving the is_special check to just before we print out
the special variable name.
