Subject: [PATCH net-2.6.25 1/19] [NETNS] Add netns parameter to fib_rules_(un)register.

The patch extends the different fib rules API in order to pass the network
namespace pointer. That will allow to access the different tables from
a namespace relative object. As usual, the pointer to the init_net variable
is passed as parameter so we don't break the network.
