ipv6: lockless IPV6_MULTICAST_LOOP implementation
Add inet6_{test|set|clear|assign}_bit() helpers.
Note that I am using bits from inet->inet_flags,
this might change in the future if we need more flags.
While solving data-races accessing np->mc_loop,
this patch also allows to implement lockless accesses
to np->mcast_hops in the following patch.
Also constify sk_mc_loop() argument.
