ipv6: use newly introduced __ipv6_addr_needs_scope_id and ipv6_iface_scope_id
This patch requires multicast interface-scoped addresses to supply a
sin6_scope_id. Because the sin6_scope_id is now also correctly used
in case of interface-scoped multicast traffic this enables one to use
interface scoped addresses over interfaces which are not targeted by the
default multicast route (the route has to be put there manually, though).
getsockname() and getpeername() now return the correct sin6_scope_id in
case of interface-local mc addresses.
v2:
a) rebased ontop of patch 1/4 (now uses ipv6_addr_props)
v3:
a) reverted changes for ipv6_addr_props
v4:
a) unchanged
