RFR: 8027765 Make exit codes and stdout/stderr printing from jmap/jinfo/jstack/jps consistent

[Weijun Wang]

But it's changing from stdout to stderr in the webrev. At least GNU 
believes [1] it should go to stdout. It make the output more'able.

Also, I am not sure if

   int exit = arg1.equals("-help") || arg1.equals("-h") ? 0 : 1;

really does what it intends to. Cannot remember the precedence order of 
all these operators. I would add parentheses.

Thanks
Max
