Add support for getting nanosecond time stamp resolution when capturing.
If we have pcap_set_tstamp_precision(), use it to request nanosecond time stamp resolution *if* we're writing a pcap-ng file; any code that reads those files and can't handle nanosecond time stamp resolution is broken and needs to be fixed. If we're writing a pcap file, don't ask for nanosecond resolution time stamps, as that requires a different magic number for pcap files, and not all code that reads pcap files can handle that. (Unlike pcap-ng, where the ability to have non-microsecond time stamp resolution was present from Day One, it's a relatively recent addition to pcap.) We could add a command-line option/GUI option for that, like the option recent versions of tcpdump have, if it matters.
