Fixed worker_shutdown_timeout in various cases. The ngx_http_upstream_process_upgraded() did not handle c->close request, and upgraded connections do not use the write filter. As a result, worker_shutdown_timeout did not affect upgraded connections (ticket #1419). Fix is to handle c->close in the ngx_http_request_handler() function, thus covering most of the possible cases in http handling. Additionally, mail proxying did not handle neither c->close nor c->error, and thus worker_shutdown_timeout did not work for mail connections. Fix is to add c->close handling to ngx_mail_proxy_handler(). Also, added explicit handling of c->close to stream proxy, ngx_stream_proxy_process_connection(). This improves worker_shutdown_timeout handling in stream, it will no longer wait for some data being transferred in a connection before closing it, and will also provide appropriate logging at the "info" level.
