Revision 790587

Security fix for CVE-2009-1890:

* modules/proxy/mod_proxy_http.c (stream_reqbody_cl): Specify the base
  passed to apr_strtoff, and validate the Content-Length in the same
  way the HTTP_IN filter does.  If the number of bytes streamed
  exceeds the expected body length, bail out of the loop.

Thanks to: Toadie <toadie643 gmail.com> for reporting and diagnosis of
	this issue.
