Removed winpcap and cleaned up network module selection.
(nw) The pcap.h header itself has the problematic original BSD license,
including the obnoxious advertising clause. Using tap/tun networking on
Windows provides a much better experience, so the extra setup is worth
it. This patch also allows you to enable pcap on platforms where it's
disabled by default with USE_PCAP=1 if you really want to use it.
