  Noticed in the development of fips-enabled mod_ssl, when we are
  configured to support exactly one protocol, use that explicit server
  and client mechansim to handshake with the client or proxied machine,
  rather than the generic SSLv23_[client|server]_method().

Update CHANGES to reflect that worker now supports graceful-stop, that Bill
wrote some of the graceful-stop code I stole from Ken, and to get rid of
exraneous `'`'s.

Implement a graceful-stop for the worker MPM. We close our listeners, and then
ask each child process to do the same. We then monitor until all children have
exited.

The change to ap_start_shutdown(void) to ap_start_shutdown(int) may look like
an external API change, but the function is defined static, and used only in
one place.

CGId keeps a copy of the listening sockets open, which interferes with a 
graceful shutdown/start. Close the listening sockets on cgid start.

Remove as many ghastly scoreboard loops from the graceful-shutdown code, and
replace with the new ap_relieve_child_processes() call. Add a sleep() call now,
as we lost the timeout inherent in ap_wait_or_timeout(). 1 second seems a sane
choice.

Implement a "graceful-stop" for the prefork MPM (might aswell do the hard one
first). 

General approach is to send SIGUSR1 to all children (which will de-listen, and
exit when finished), and to gather all children as they exit. 

We don't use a sleep(timeout) for the timeout implementation, because this
would lead to a rut of defunct children until the timeout had expired.

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.
