[CAN]: Add virtual CAN netdevice driver

This patch adds the virtual CAN bus (vcan) network driver.
The vcan device is just a loopback device for CAN frames, no
real CAN hardware is involved.

+          Similar to the network loopback devices, vcan offers a
+          virtual local CAN interface.
+
+          This driver can also be built as a module.  If so, the module
+          will be called vcan.

+          Say Y here if you want the CAN device drivers to produce a bunch of
+          debug messages to the system log.  Select this if you are having
+          a problem with CAN support and want to see more of what is going
+          on.
