Summary:                    pidof, make -s optional and add optional -o
Description: 
For pidof, i want to make support for option -s (single shot) optional
instead of unconditional as it is now.
Also, this adds optional support for option -o (omit given pid).

Please consider reviewing and applying.
Thanks to Vladimir for pointing out alot of errors i managed to make.

If -s and -o are not compiled into pidof.o.new, size stats are:
   text	   data	    bss	    dec	    hex	filename
    262	      0	      0	    262	    106	pidof.o.oorig
    236	      0	      0	    236	     ec	pidof.o.new

and in the cleanup, i foobared again.. :-(
The cleanup is obviously depending on the OMIT flag.

#ifdef CONFIG_FEATURE_CLEAN_UP
#ifdef CONFIG_FEATURE_PIDOF_OMIT

Sorry for that.

Correct macro for "option" in usage.h.
Make cleanup of omit dependant on CONFIG_FEATURE_PIDOF_OMIT.
Use llist_free() as introduced in issue http://busybox.net/bugs/view.php?id=204.
