If we have "pcap_freecode()", use it to free the instructions for a BPF
filter after installing the filter.
Set HAVE_PCAP_LIB_VERSION if we're building with WinPcap 3.1; it's not
present in earlier versions, but is present in current 3.1 betas.
Check HAVE_PCAP_LIB_VERSION when building capture-wpcap.c.
