Rework handling of I/O via select() to use correct fd_set type instead of int for fd sets.

Browse Source 
Some code that was maintaining an fd_set with only a single fd was replaced
       with just the fd as int, which can be added to the global fd_set as needed.
       More testing is required for less usual configurations such as host TCP/UDP/IP
       and direct ethernet (packet filter or NIT) I/O.
