Approved by dugsong@ first round of Nmap contributed modifications:
- Preserve the alias qualifier from interface name in more cases
- Set SO_BROADCAST flag on interface list descriptor so broadcast/network IPs can be investigated.
- Update _match_intf_src so it checks interface aliases for given source addr rather than only the main interface address
