ipv6: provide addr and netconf dump consistency info
This patch adds a dev_addr_genid for IPv6. The goal is to use it, combined with dev_base_seq to check if a change occurs during a netlink dump. If a change is detected, the flag NLM_F_DUMP_INTR is set in the first message after the dump was interrupted. Note that only dump of unicast addresses is checked (multicast and anycast are not checked).
