can: netlink support for bus-error reporting and counters
This patch makes the bus-error reporting configurable and allows to retrieve the CAN TX and RX bus error counters via netlink interface. I have added support for the SJA1000. The TX and RX bus error counters are also copied to the data fields 6..7 of error messages when state changes are reported.
