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.
