KWSys: List processes with "ps -ef" on OpenSolaris

In order to kill process trees we need to list all processes to find
those whose parent we are killing.  We implement process listing on
OpenSolaris by using "ps -ef" and parsing the resulting format:

     UID   PID  PPID   C    STIME TTY         TIME CMD
     %*s    %d    %d   %*[^\n]\n
