Update the documentation for the ScriptSock directive to match the
.PID extension.

Append the .PID to the ScriptSock filename. This change ensures that multiple
running instances of httpd will not clobber each others script sockets. 

Because a different socket will be created for each instance, this change also
unlinks the script-socket on exit, to prevent pollution. 

unlink() happens from within the parent process, since the change in userid's
means the cgid process likely won't have the correct permissions.

Implement "de-listening" for graceful restarts with the prefork MPM. With this
change;

  1.) httpd -k graceful sends SIGUSR1 to the parent pid, which in turn
      sends SIGUSR1 to all of the active children,

  2.) Active children each close their copy of listener fd's.

This means that the listening sockets are freed for re-use. In the ordinary
case, this makes no difference. However if for example admin changes "Listen
80" to "Listen 81" in the config, this rev makes port 80 immediately available
(no waiting for the graceful children to die).

Provide a function for closing all of the listeners. 

  * This is useful for properly implementing a graceful stop and restart
    where we want child processess to be able to carry on serving a request 
    but "de-listen" from a port. So that another instance entirely can be 
    started in our place, or to unbind from a "Listen" directive an admin 
    has removed from the configuration.
