Change semantics of ap_child_table somewhat. Instead of checking for a

Win32: Revamp NT shutdown code. I think this shutdown code is pretty close
to production ready. Introduce a two-phase shutdown. First phase is
shutdown_pending which prevents new contexts from being queued to the
AcceptEx completion port. The server runs for a period (~1 second)
in this state to enable threads to drain the completion port of active
connections by handling the connections. This works very well on a busy
server as the contexts are consumed quickly and completely (leaving non
to cancel in the next phase).
The next phase is the workers_may exit phase, which prevents threads
from blocking on the completion port (especially important to prevent
threads unblocking off of keep-alive connections from calling
GetQueuedCompletionStatus). One we enter this phase, all threads blocked on the
port (we track the number carefully) are unblocked and allowed to exit.
Then we cancel any pending i/o completion contexts on the listeners (those which
were not consumed naturally in the shutdown phase). Then we reap the ABORTED
completion packets off the port. (Possible to reap a few good "accepted"
connections here also. Oh well...). Once we are done reaping completion packets,
we release the start mutex which allows the new child (in a restart) to
begin accepting connections.
It is really REALLY important to not let multiple processes call
GetQueuedCompletionStatus at the same time. Results are unpredictable.
Another day's progress... little changes, but just establishing the
baseline for fully implementing extensions. Filters... that's still
a little way away. This demonstrates the HSE_STATUS_PENDING result
wait event trap, so we let another thread keep working till we get
the HSE_REQ_DONE_WITH_SESSION request. Cleaned up callback names
and tossed bunches of stuff in the isapi_cid (connection/request) and
the isapi_loaded (dll details) for future caching optimizations.
