Fix a buglett in backport 230718; get our selection of brigades correct.

  (tis what happens when our code is this far out-of-sync with trunk, sorry.)

git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/branches/proxy-reqbody-2.0.x@230720 13f79535-47bb-0310-9956-ffa450edef68

  Backport fix r230718; a soon-to-be impossible edge case; we are always
  sending a body (even an 'empty' body) using stream_chunked, so we must
  always send the trailing "0" end of body marker.


git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/branches/proxy-reqbody-2.0.x@230719 13f79535-47bb-0310-9956-ffa450edef68

  Finish up the header brigades up-front; we simply know ahead of time if
  they are necessary or not.  This changes one behavior; the stream_chunked
  now always sends a transfer encoded body; even if it's nothing but an
  empty body.

  Also, Fix a bugglet in backporting the input_brigade argument; need the
  bucket_alloc already.

git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/branches/proxy-reqbody-2.0.x@230716 13f79535-47bb-0310-9956-ffa450edef68

  Pre-commit a simple bit from r219224, pass an initialized input_brigade
  off to the spool/stream functions.  Effectively a no-op so far, but in
  a couple of patches, the reason becomes obvious.


git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/branches/proxy-reqbody-2.0.x@230714 13f79535-47bb-0310-9956-ffa450edef68

  Backport a logging change to make things clearer; includes jorton's r224721 fix.

git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/branches/proxy-reqbody-2.0.x@230712 13f79535-47bb-0310-9956-ffa450edef68

  Backport part of r216156 and very minor bits of r218978;

  Collapse the handling of Content-Length / Transfer-Encoding header
  values into the headers loop saving a bit of cpu and making the
  results clearer, handle the (r->main) subrequest case a bit more 
  efficiently as well, cutting out some duplicate tests, and a mild
  whitespace issue in the If-Unmodified-Since test line.

  Fixes a subrequest bug where subrequests *still* would attempt to
  read Transfer-Encoding: chunked request bodies.

  Backport part of r216156;

  send_request_body makes it very difficult to follow all the mistakes
  in this code.  Fold send_request_body into ap_proxy_http_request
  so that proxy_http_request makes all of the elections.

  End apr_natstrcasecmp, backporting part of r216111 (there may remain
  other apr_natstrcasecmp abuse in other files).

  Still unsure if apr_strnatcasecmp of the hostname is deliberate to
  handle leading 0's in ip addresses, so leaving that single use case.

  Now backport whitespace-only changes from r209836, making the rest of
  the patches more legible, and the resulting code comparable   to httpd/trunk/modules/proxy/mod_proxy_http.c.

git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/branches/proxy-reqbody-2.0.x@230706 13f79535-47bb-0310-9956-ffa450edef68

  Prepare to backport r209836 whitespace changes; this is the one
  minor code change to declare *buf once, obliterating the need for
  a number of code blocks throughout this function.
