More uses of ap_map_http_request_error() and AP_FILTER_ERROR so that we never return an HTTP error status from a handler if some filter generated a response already. That is, from a handler, either ap_get_brigade() (an input filter) returned AP_FILTER_ERROR and we must forward it to ap_die(), or ap_pass_brigade() (an output filter) failed with any status and we must return AP_FILTER_ERROR in any case for ap_die() to determine whether a response is needed or not. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1665625 13f79535-47bb-0310-9956-ffa450edef68
