Update the DirectoryServer class so that the server.pid and server.starting
files will be marked for deletion as soon as possible.  This will help the
start-ds script to exit more quickly in the event that the provided set of
command-line arguments was invalid, as well as the case in which a valid set of
arguments was provided but the server should not actually be started (e.g.,
"--version").
