This patch adds support for IP_TRANSPARENT support for listening sockets in the http module and stream module. Adding `transparent` to ths options of a listen directive, IP_TRANSPARENT will be enabled on that listening socket, allowing it to accept traffic redirected using TPROXY. When this is enabled, the original destination IP address and port before the redirection can be fetched from the variables $server_addr and $server_port. The original version of this patch was proposed by Stijn Tintel in <https://trac.nginx.org/nginx/ticket/287>. Signed-off-by: Miao Wang <shankerwangmiao@gmail.com>
