The GNU-specific option -a lets xargs read the arguments from a file
rather than from stdin.
This is particularly convenient when debugging in gdb interactively,
and it might be of more general use.

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.
Tested by building on systems with and without i2c-tools headers.

Using a negative pid to send TERM to a process group results in an
obscure error:
$ ./busybox kill -12345
kill: bad signal name '12345'
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.
However, we did not support "--". Add this capability to BusyBox.

minips is a pure alias to ps, just in case someone needs 100% klibc-utils compat.
nuke is a primitive version of "rm -rf" without options and error checks. ~30 bytes.
resume is a tool for initramfs which resumes from a given block device.
