Updating level 1 commands.
exit - correctly convert the parameter to the return code. for - update string-to-number conversion. if - use shell string-to-number conversion and add comments. stall- add command main lib files: add comments, clarify user visible strings, add stall. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11420 6f19259b-4bc3-4df7-8a09-765794883524
