[NETFILTER]: Add CONFIG_NETFILTER_ADVANCED option
The NETFILTER_ADVANCED option hides lots of the rather obscure netfilter options when disabled and provides defaults (M) that should allow to run a distribution firewall without further thinking. Defaults to 'y' to avoid breaking current configurations. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
