Log Message:
allow IP_MULTICAST_IF and IP_ADD/DROP_MEMBERSHIP to specify interface
by interface index.  if the interface address specified is in 0.0.0.0/8
it will be considered as interface index in network byteorder.

getsockopt(IP_MULTICAST_IF) preserves old behavior if
setsockopt(IP_MULTICAST_IF) was done with interface address, and
returns interface index if setsockopt(IP_MULTICAST_IF) was done with
interface index (again using the form in 0.0.0.0/8).

Suggested by Dave Thaler, based on RIPv2 MIB spec (RFC1724 section 3.3).
