[IPV6]: Seperate sit driver to extra module
This patch removes the driver of the IPv6-in-IPv4 tunnel driver (sit)
from the IPv6 module. It adds an option to Kconfig which makes it
possible to compile it as a seperate module.

+ Tunneling means encapsulating data of one protocol type within
+ another protocol and sending it over a channel that understands the
+ encapsulating protocol. This driver implements encapsulation of IPv6
+ into IPv4 packets. This is useful if you want to connect two IPv6
+ networks over an IPv4-only path.

+ Saying M here will produce a module called sit.ko. If unsure, say Y.
