bug#18487: `server-running-p' not autoloaded

[Emilio Lopes <eclig@gmx.net>]

The function `server-running-p' is not autoloaded.  That means that
the following code in
the user's init-file will result in an error:

    (unless (or noninteractive
                (server-running-p))
      (server-start))

On the other hand, `server-start' doesn't signal an error if called
when a server process is already running.
So the test using `server-running-p' is indeed not necessary (anymore?).

Anyway, the following patch adds the `autoload cookie' for `server-running-p':
