Oversight in commit b8cc8f9. I just noticed this causes compiler warnings on FreeBSD, and it really ought to cause warnings elsewhere too: all references I can find say that <arpa/inet.h> is required for these. We have a lot of code elsewhere that thinks that both <netinet/in.h> and <arpa/inet.h> should be included for these functions, so do it that way here too, even though <arpa/inet.h> ought to be sufficient according to the references I consulted. Back-patch to 9.4 where the previous commit landed.
