This will help us avoid a malloc/free pair when executing mod_rewrite
rules that use $1/$2/etc to reference sequences in the matched pattern.

Note: I've also submitted this change as a patch for PCRE, but because
the next PCRE release isn't planned until later this year I'm

  Here's the patch that really sucks.  old_listeners points to an array
  of apr_socket objects already destroyed by their cleanups, and in any
  case they now live in invalid memory.  Extend their lifetimes.

  This implies that the process pool grows on every restart for no good
  reason.  One possible solution is to let the old pconf survive until
  the new pconf is alive.  Another is to create the listeners in a subpool
  of process->pool, destroyed after the old_listeners are closed.

  Either which way, a better solution exists, but this closes the immediate
  bug.  [How haven't we been segfaulting in unix on restarts before this
  patch, gurus?]

cleanly at graceful restart time.  This is a basic requirement of
reliable graceful restarts (the kind that won't drop connections).
This allows a future fix to make worker threads hang around until
they service all connections previously accepted by the listener
thread.

The old mechanism of doing a dummy connection to wake up the
listener thread in each old child process didn't work.  It didn't
guarantee that (in the main thread) the byte was read from the pod
and global variables were set before the listener thread grabbed
the connection.  It didn't guarantee that a child process in the
new generation didn't get some of the dummy connections.

Rather than burn extra syscalls adding a unique socket or pipe
to the poll set (and breaking single listen unserialized accept
in the same change), this uses a signal sent from the main thread
to the listener thread to break it out of the poll or accept.
(We don't worry about breaking it out of the optional mutex because
the child process holding the mutex will break out of poll/accept
and release the mutex, allowing a child blocked in the mutex to
get it.  Eventually all children blocked in the mutex will come
out.)

Since the listener thread now exits reliably, the main thread
joins it.

previously, after a non-graceful restart followed by a terminate

sending SIGTERM and finally SIGKILL to one or more children...
