  1. mldq6: fix default sleep interval, to adhere to RFCs 

    The default MLD querier interval according to RFC2710 and RFC3810 is 125
seconds, not 120.

  2. mldq6: implement MLDv2 Queries and use v2 by default 

    Next to the already implemented MLDv1 Queries (RFC2710) this now
implements MLDv2 Queries (RFC3810). And uses MLDv2 Queries by default,
unless specified otherwise with the new --mld-version|-V option.

The MLDv2 QQIC is calculated internally from the --sleep option (which
defaults to 125). Other than that the MLDv2 Query S-Flag (--mld-sflag|-M)
and QRV (--mld-qrv|-R) values can be configured.

MLDv2 Query messages for "Multicast Address and Source Specific Queries"
are not yet implemented and still to do. Therefore the "Number of Sources"
field is not configurable yet either.
