can-gw: add netlink based CAN routing
This patch adds a CAN Gateway/Router to route (and modify) CAN frames. It is based on the PF_CAN core infrastructure for msg filtering and msg sending and can optionally modify routed CAN frames on the fly. CAN frames can *only* be routed between CAN network interfaces (one hop). They can be modified with AND/OR/XOR/SET operations as configured by the netlink configuration interface known e.g. from iptables. From the netlink view this can-gw implements RTM_{NEW|DEL|GET}ROUTE for PF_CAN. The CAN specific userspace tool to manage CAN routing entries can be found in the CAN utils http://svn.berlios.de/wsvn/socketcan/trunk/can-utils/cangw.c at the SocketCAN SVN on BerliOS.
