- substr used in APACHE_MODULE for the help string did not parse correctly
  with autoconf 2.50+ so we had to punt there anyway and use AC_HELP_STRING.
- Add APACHE_HELP_STRING define that will call AC_HELP_STRING on 2.50+
  (actually not 2.13 - look at the regex call) or do our custom variation
  of it.  This function can't have any extra spaces or it will be returned
  in the help string.  So noted.  If anyone can figure out how to insert
  a line break like 2.50+ does when we go over the 26th column, I'd
  appreciate it.  I tried and I'm way too tired to figure it out now.
  Adding this would greatly simplify two or three HELP_STRING uses.
- Switch all of those annoying WITH and ENABLE functions to use the
  APACHE_HELP_STRING.  This makes everything consistent now.  I've always
  had to go through and keep aligning everything every few months or so
  because I'm the only one who cares.  No more.  I refuse to do it any more!
  Use APACHE_HELP_STRING or be crucified.

Looks decent with autoconf-2.13 and autoconf-2.52.

so I'm applying each of the new patches one by one (there are only a few of
them) so that the new mod_proxy.html file is up to date.
This first patch returns the original doc to the tree. Subsequent patches
will apply the changes to the file up to date.

filter until after we have read the headers.  This eliminates the status
hack that was in http_protocol.c and makes it all around better.

server/protocol.c now directly adds HTTP_IN filter - should we create a
specific hook for this?  (Could we do this as a post_read_request hook?)
I'm not terribly sure, but let's move it down to the lowest possible
place in ap_read_request.  We can change this detail later as we see fit.

rearranging and rethinking some things.  The net result is that the HTTP
filter is now a request filter and is now only responsible for HTTP things.
The core input filter is now responsible for handling all of the dirty work.

Highlights:
- Removes the dechunk filter and merges it with ap_http_filter (aka HTTP_IN).
  The dechunk filter was incorrectly handling certain cases (trailers).
- Moves ap_http_filter from a connection filter to a request filter
  to support the consolidation above (it needs header info).
- Change support code to allow the http_filter to be a
  request filter (how the request is setup initially).
- Move most of the logic from HTTP_IN to CORE_IN (core_input_filter).
  HTTP_IN is now only concerned about HTTP things.  The core filter
  is now responsible for returning data.  It is impossible to
  consolidate dechunk and http without this because HTTP_IN previously
  buffered data.  As Greg has suggested, it may make sense to write
  some brigade functions that handle input (getline).  It should be
  fairly trivial to add these.  Some of the calls in ap_http_filter
  could be switched as well.

This is the original patch as submitted to dev@httpd on Monday, Sep.
24th.  Additional comments and some minor tweaks done after that
submission are coming up next.  This should allow people who reviewed
the original patch to see what has changed and review them piecemeal.

This test passes all current tests in httpd-test.  Please perform
chicken sacrifices to verify that this hasn't blown up your favorite
input.

If we are *already* a faux URI (i.e. relative file sub req) and we then
make a subrequest from that faux URI to a file in the same directory,
we'd try to build a URI out of the fake URI which leads to the wrong
thing happening somewhere down the line.  So, let's just give this
special case a fake URI as well.

OtherBill needs to verify this.  He can back it out if he wants.  I
don't much care.  It's one line and it seems okay...

  MAJOR charset encoding fixes.  The file names and HTTP-Equiv tags are now
  in sync with the httpd-std.conf - and the ucs2/4 encodings are gone since
  utf8 is a universally recognized shorthand that sits much better in our
  tree [notice; these were _duplicate_ character sets, only in different
  byte encodings!]  Same with removing the duplicate .jis and .is-kr files.
  [I simply choose the one 'with link' over the one without, and fixed the
  links back to preFAQ as I picked.]

  Russian users, how many of the remaining five encodings are truly needed?

  Overhaul the compatibility with 1.3's subrequest and redirect processing.

  Eliminate URI-centric phases in ap_process_request_internal() for pure
  file subrequests (that don't correspond to URI space.)  translate_name
  hook and location_walks are skipped for these requests.

  Moves the reset of the per_dir_config out of directory_walk into the
  internal request processing code, so that resources with alternate
  map_to_storage requirements start with clean r->server->lookup_defaults.

  Optimizes out the authn/authz of effectively identical subreqests and
  redirects, as the sub_req_lookup calls once did.  Unlike 1.3, we copy
  r->user and r->ap_auth_type from main/prev for the request's reference.

  Stop copying the subrequest's r->chunked flag (Rbb assured me it looked
  bogus, chunking is on the parent request) and clean out other #if 0'ed
  cruft we don't need to refer back to anymore.
