If we do not know a C-T for a subreq, we *must* propogate that
non-knowledge upwards to the main request.

Previously, if you used a DirectoryIndex with a file without a C-T (say
.shtml without AddType), the r->content_type will be kept as
httpd/unix-directory when we promoted the subreq in mod_dir.  Since there
would be no handler on this file, ap_invoke_handler (config.c:355) would
set the handler to be httpd/unix-directory (which was the old C-T of the
dir).  This would then trigger the handler to become httpd/unix-directory.
mod_autoindex would then try to serve the request.  But, the filename
was propogated upwards by mod_dir's DirectoryIndex via
internal_fast_redirect - it would then return a 403 trying to generate a
mod_autoindex page for a file.

Now, we will use ap_default_type() which is correct.

The threadpool MPM implements Aaron Bannert's "time-space tradeoff"
design managing idle workers.  Rather than putting accepted connections
into a queue, the threadpool MPM keeps idle worker threads in a stack.
Its dedicated listener thread retrieves an idle worker from the stack
before accepting a connection.  If there are no idle workers, the
listener blocks until a worker becomes available before doing an accept.

In many ways, threadpool is also a variant of leader/follower.  They
both maintain a stack of idle threads.  The difference is that threadpool
has a dedicated listener thread, and leader/follower rotates the listening
responsibility among its worker threads.  In my initial testing, the
leader/follower MPM performs very well on multiprocessor Solaris 8 when
listening on a single port, but poorly when listening on multiple ports.
(I don't know why this is happening.  What I've found so far is that
when you add a poll on the listen socket(s) before the accept in the
leader/follower MPM, all the socket-related syscalls in the httpd get
slower.  My hypothesis is that the thread scheduler is making an optimal
decision about where (on what CPU) to run the newly awakened thread if
its first syscall is an accept, and a nonoptimal decision if its first
syscall is a poll.)  The threadpool MPM performs better with multiple
listener ports, and in my testing so far it looks competitive with
leader/follower when running with a single listener.

config.guess/config.sub files to be identical.  Previously, we had three
different versions of the guess files - now they are the same.

I attempted to merge in ASF changes that were marked and still needed.
Please verify that these work on your platform.  (Particular attention
is required for the IBM platforms.)

Part of PR 7818 stems from the fact that the bundled expat did not have an
included config.guess/config.sub.  Therefore, it would take the config.guess
from the system.  Icarus's autoconf/libtool is very old (2.13/1.3.5).  The
machine that was used to roll 2.0.32 had a recent autoconf/libtool which
explains the behavior that Sander saw in the PR.  Therefore, we now
explicitly provide a config.guess/.sub for the bundled expat so that
all of the versions are in sync.  This should minimize configuration
problems.

pcre was using a config.guess that was imported when Brian made the 3.9
import.  It did not have the Apache modifications, but seems to have
had the Darwin changes.  Go figure.  Sync it up as well.

This requires some reshuffling of the code in http_protocol.c so
that some static declarations are available early enough in the

The equivalent logic was deleted when request filters were renamed to
RESOURCE filters.  This fixes the seg faults that sometimes happen on
daedalus after a bogus 416 HTTP response is generated.

In this case, includes_filter had found an <!--#include virtual > tag, and
sent a brigade representing the data before it down the filter chain.  The
byterange filter generated the bogus 416.  ap_send_error_response essentially
starts over with a new response, but it didn't do anything to clean up the
filter chain.  So the same instance of the includes_filter got driven from the
top with the canned error text and and EOS bucket, which confused the heck
out of it.  It inserted a sentinel from the original brigade into the
error page brigade, causing problems further down the filter chain.

Previously, request that sent:

GET / HTTP/1.1
Host:

would get a 400.  RFC 2616 specifically allows for a "blank" host field.

The read_request code properly handled this, but the fix_hostname in
vhost.c would cause the 400.  Now, simply return in fix_hostname when
we see a blank hostname rather than erroring out.
