passed to ap_note_subprocess() by mod_rewrite and mod_include.  The
storage needs to last as long as the pool passed to
ap_note_subprocess(), so autodata won't work.

The mod_rewrite change wasn't tested.  A normal build with mod_rewrite
on Linux currently results in the link failing due to unresolved
references to dbm_*.

we decide on a prototype for the function causing the warning.  That
decision is tied to which filtering mechanism we decide on.

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.

. dexter/scoreboard.c needed apr_strings.h to get the right
  function prototypes

. main/mpm_common.c needed to recognize that we were building
  for dexter; otherwise, no ap_reclaim_child_processes() was
  compiled and linking failed

(It would be nice to standardize on which preprocessor symbols
are checked for...  mpmname_MPM seems nice enough.  Didn't the
check for symbol mpmname (no "_MPM") come with mpmt.c?)

When preparing to call iol_sendfile(), don't call ap_bflush() first.
Instead, pass the data ap_bflush() would have written (if any) to
iol_sendfile() as a header.  In practice, this prevents sending headers
separately from the first part of the file.
