Don't write the SP_SUCCESS messages unless -Z was specified.

Add support for a machine-readable "-v" output, which prints only the
pcap version string.

Give a little more information about the machine-readable format, but
note that it's primarily intended for consumption by Wireshark and
TShark and is subject to change.

Properly hyphenate "pcap-ng".
