Use rcu_assign_pointer/rcu_dereference for ip_ct_attach pointer instead
of self-made RCU and use rcu_read_lock to make sure the conntrack module
doesn't disappear below us while calling it, since this function can be
called from outside the netfilter hooks.

This patch doesn't introduce any code changes, but merely splits the
core netfilter code into four separate files. It also moves it from
it's old location in net/core/ to the recently-created net/netfilter/
directory.
