Sync to httpd/trunk where we've reverted the /d "LONG_NAME=foo bar" syntax,
  which confuses the ability of MS VS 6 to export makefiles.

  Also syncs the fix to some debug/release targets observed by hunter.

Vote on the PCRE backport; While it is 3rd party software, we must take responsibility for it when we are distributing it. The choice to not include it should be discussed on dev@httpd, or voted on separately.

* Keep the Content-Type for successfully revalidated
  cached objects, by unsetting possible Content-Type headers in
  r->headers_out and r->err_headers_out as they may be different to what
  we have received from the cache.
  Actually they are not needed as r->content_type set by
  ap_set_content_type a few lines above will be used in the store_headers
  functions of the storage providers as a fallback and the HTTP_HEADER filter
  does overwrite the Content-Type header with r->content_type anyway.

* Add optional 'scheme://' prefix to ServerName directive.  For
  'https', mod_http returns "https" for the ap_hook_http_scheme and
  DEFAULT_HTTPS_PORT for ap_hook_default_port.  This fixes Redirect
  responses to requests for directories without a trailing slash
  when httpd runs behind a proxy or offload device that processes
  SSL.  It also enables support for Subversion in that
  configuration.  This change is completely backwards compatible
  and passes the perl-framework.  Minor mmn bump because I add a
  field to server_rec.

* Document r399947, addition of optional scheme:// to ServerName directive

* Handle the cases "no proxy request" and "reverse proxy request" in the same
  manner, when setting scheme and port_str. This is needed because if a cached
  entry is looked up by mod_cache's quick handler r->proxyreq
  is still unset in the reverse proxy case as it only gets set in the
  translate name hook (either by ProxyPass or mod_rewrite) which is run
  after the quick handler hook. This is different to the forward proxy
  case where it gets set before the quick handler is run (in the
  post_read_request hook).
  If a cache entry is created by the CACHE_SAVE filter we always have
  r->proxyreq set correctly.
  Also set scheme to ap_http_scheme(r) instead of "http" to handle SSL
  correctly.

* Fix const compiler warning introduced by r407357.
Noticed by: Joe Orton

* Cleanup the code by replacing some inline code to lower-case a string with
  ap_str_tolower.
