the use of CancelIo on the listen socket. Threads can only cancel
their own I/O. To enable use of this nifty feature, I needed to make
sure only one thread ever initiated async I/O. So, if the workers
detect that they need more completion contexts (async AcceptExes),
they set the maintenance_event, which directs the control thread to
do the work on behalf of the workers. Most of the other changes are
to support this end.

    pass the first child, rather than expecting the walker to do it.
remove the nasty "static" variable inside ap_walk_config(). it now walks the
    tree provided with no worries about bumping up/down levels.
minor refactor between ap_walk_config() and ap_walk_config_sub() to clean up
    some logic and clarify the code.

    add directive.
move configfile_t and functions from httpd.h to http_config.h
new signature for ap_build_config() (since config_file removed from cmd_parms)
add "data" to ap_directive_t for future use by modules. add filename.
syntax checking for section-close directives: a section-open must exist,
    the section-close must be </FOO>, and the open/close must match.
    the file as a whole must be properly balanced (issue errors for each
    unmatched section-open).
</FOO> command_rec structures are obsolete. Remove from http_core.c.
do not store </FOO> directives in the config tree.
clean out section-close logic from http_core.c (and old, related comments)
<Limit> and <LimitExcept> must walk their children.
new mechanism in ap_check_cmd_context() for testing enclosure in a
    Directory/Location/File: find_parent()
<IfModule> and <IfDefine> must pass cmd->context when walking the children
several places: we had a walk followed by ap_get_module_config(). that
    assumed the walk would create a config that we could fetch, which is not
    true -- it is possible that the children are all from other modules
    (e.g. the <Files> section in httpd.conf-dist has no "core" directives).
    using ap_set_config_vectors() ensures we get a structure, and it returns
    it to us.
    [ note: when we had </Directory> (and friends) in the tree, the config
      would get created; removing the directive removed the config; this
      was a bitch to track down :-) ]

add missing return statements, wrap some lines, remove unused vars.
move syntax error reporting and exit(1) back to the right place (to be
    fixed in a future pass; the exit() is inappropriate for parsing
    .htaccess files).

Unix systems that implement sendfile.

It is still very rough around the edges (compile warnings, does an unnecessary
stat, not completely Unix friendly, leftover mod_mmap_static code, etc.)

ap_canonical_errror() for Unix now maps EWOULDBLOCK to EAGAIN/APR_EAGAIN
when appropriate so that the changes here (as well as bjh's changes from a
few days ago) to call ap_canonical_error() before comparing with EWOULDBLOCK
will work on Unix as well.

Add a pool to dupfile.  There is no reason that when we duplicate a file,       we would want to use the same pool for the duplicated file as we used for
the original file.  This should solve a problem we were having with
dieing quietly on startup, because we are no longer closing stderr in the
original process and then opening the config file as file descriptor 2.

The original problem report can be found in the message
