1. Add Ipv{4,6}PacketInfo support to ControlMessage for send{m,}msg …

   This adds Ipv4PacketInfo and Ipv6PacketInfo to ControlMessage,
   allowing these to be used with sendmsg/sendmmsg.
   
   This change contains the following squashed commits:
   
   Add Ipv{4,6}PacketInfo to ControlMessage.
   
   Add documentation links to Ipv{4,6}PacketInfo
   
   Add changelog entry for Ipv{4,6}PacketInfo
   
   Add link to PR in the Changelog.
   
   Add extra build environments.
   
   Add tests for Ipv{4,6}PacketInfo.
   
   Swap #[test] and #[cfg]
   
   The CI appears to be running the test, even though it's not cfg'd for
   that platform.  I _think_ this might be due to these being in the wrong
   order.  So lets try swapping them.
   
   s/freebsd/netbsd/ for Ipv4PacketInfo
   
   netbsd supports in_pktinfo, not freebsd.
   
   Fix the cfg for Ipv{4,6}PacketInfo usage.
   
   Ah, I see what I did wrong.  I had fixed the definitions, but I had the
   wrong cfg() in the usage.  This has the usage match the definitions.
   
   Change SOL_IPV6 to IPPROTO_IPV6.
   
   FreeBSD doesn't have SOL_IPV6, but does have IPPROTO_IPV6, and the two
   constants are defined as being equal.  So change to use IPPROTO_IPV6.
   
   Skip Ipv6PacketInfo test if v6 is not available.
   
   If IPv6 is not available, then when we try and bind to ip6-localhost,
   we'll get a EADDRNOTAVAIL, so skip the test.
   
   This should mean that the test will run on any machine that has a v6
   loopback address.
   
   More architecture cfg() fixes.
   
   These all need to be the same, and they were not.  Make them them all
   the same.  Attempt III.
   
   Fix up mismatched cfg's again.
   
   Take IV.  Make sure the cfg's that use a enum variant match the enum
   definition.
