Uthernet II: add extended feature to virtualise DNS requests. . This allows pure TCP/UDP sockets to run *without* MACRAW requests (and so without libpcap). . Raw sockets will not work. . Add configuration for Virtual DNS. libpcap: ensure all functions check if the library is loaded before using it. Uthernet 1: do NOT overwrite tfe_cannot_use as it should only reflect the availability of npcap on *this* system. Add Copyright notice, and mention Virtual DNS in html.
