At one point, I remember a discussion resulting in the official name of the next-generation replacement for pcap format being changed to "pcapng", with no hyphen. Make tcpdump reflect that. While we're at it, uppdate to use "macOS" as the name of Apple's UNIX-for-Macs, as appropriate (don't use it for versions that were still called Mac OS X or OS X).
