ipv6: Nonlocal bind
Add support to allow non-local binds similar to how this was done for IPv4.
Non-local binds are very useful in emulating the Internet in a box, etc.
This add the ip_nonlocal_bind sysctl under ipv6.
Testing:
Set up nonlocal binding and receive routing on a host, e.g.:
ip -6 rule add from ::/0 iif eth0 lookup 200
ip -6 route add local 2001:0:0:1::/64 dev lo proto kernel scope host table 200
sysctl -w net.ipv6.ip_nonlocal_bind=1
Set up routing to 2001:0:0:1::/64 on peer to go to first host
ping6 -I 2001:0:0:1::1 peer-address -- to verify
