[nft PATCH] proto: Add some exotic ICMPv6 types

[Phil Sutter <phil@nwl.cc>]

This adds support for matching on inverse ND messages as defined by
RFC3122 (not implemented in Linux) and MLDv2 as defined by RFC3810.

Note that ICMPV6_MLD2_REPORT macro is defined in linux/icmpv6.h but
including that header leads to conflicts with symbols defined in
netinet/icmp6.h.

In addition to the above, "mld-listener-done" is introduced as an alias
for "mld-listener-reduction".

This should resolve netfilter BZ#926.
