0b6ec06beb kill: add '--' option to separate options from arguments
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.

ab77e81a85 klibc-utils: new applets: resume, nuke, minips
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.

61a91af63d kill: optimizations for single-applet build
* Fix a bug with a configuration in which the shell's kill builtin
  would be mistreated as a killall command (i.e. '-q' works, and
  'kill process_name' succeeds when it shouldn't):

    CONFIG_ASH_JOB_CONTROL=y
    CONFIG_HUSH_KILL=y
    # CONFIG_KILL is not set
    CONFIG_KILLALL=y
    # CONFIG_KILLALL5 is not set

* Optimize out unneeded code when the relevant applets are not
  selected.

* Move kbuild lines about shells' kill builtins from Kbuild.src to
  kill.c, to accompany the new HAVE_SH_KILL macro. I hope this would
  make maintanence a little bit easier.
