Now that we try to build libpcap with large file support, add a warning 

to users of pcap_file() that the resulting FILE * might refer to a file
> 2GB and a suggestion that they use large-file-capable calls on it or
on the result of passing it to fileno() if at all possible.

Note that the Packet Capture library is usually built with large file
support, so the standard I/O stream of the ``savefile'' might refer to

.B pcap_file()
should, if possible, use calls that support large files on the return
value of
