- Add a "state" variable to the worker_wakeup_info struct. This is
  used to make sure that we act on the correct signal, and to know when
  to shut down a worker thread.
- Fix the call when the worker thread waits for a connection to use
  the new state variable and use mutexes around the cond_wait() call.
- Change the interrupt_all() call to set the WORKER_TERMINATED state.
- Add two AP_DEBUG_ASSERT() to make sure that we aren't waking up
  a worker thread before it is idle.

- We don't need the listener_blocked flag, just check if the element
  we're adding makes the stack non-empty.
- When we are terminated, return APR_EOF; catch this event in the
  worker thread and the listener thread.
- When shutting down, always signal a potential listener thread.
- Wait to signal the listener thread until after we add the worker
  element to the stack.

fast_redirect, the filter would still point at the subreq - rather than
the original r.  So, we must update any filters pointing at rr to be r.

This would cause lots of problems with mod_include with mod_dir requests
such as seen in PR 7966.  mod_include would be unsetting the headers_out
of rr instead of r.  But, we disassociate rr->headers_out and r->headers_out.
Therefore, the C-L header in r->headers_out would remain - even though it
bears no relation to what we will be outputting - causing problems.

This also now permits chunked-encoding of mod_dir/mod_include requests
which could never happen before and fixes the content-length problem
seen in PR 7966.

As hinted at in PR 7966, there is a race condition - if for some reason
the server stalls reading an included file (or even better, placing a
sleep in the cgi-bin script!), the invalid C-L may get propogated to the
client.

(Note that internal_internal_redirect has this same code fragment.)

the listener thread from accept()ing more connections than there are
available workers. This prevents long-running requests from starving
connections that have been accepted but not yet processed.

The queue_info is a simple counter, mutex, and condition variable. Only
the listener thread blocks on the condition, and only when there are no
idle workers. In the fast path there is a mutex lock, integer decrement,
and and unlock (among a few conditionals). The worker threads each notify
the queue_info when they are about to block on the normal worker_queue
waiting for some connection to process, which wakes up any sleeping
listener thread to go perform another accept() in parallel.

elements in the queue represent accept()ed connections, we want them

converted it to a LIFO quite awhile ago in the hopes that it would
improve cache efficiency.)

since this patch changes the size of the fd_queue_t object (which is
