Single Unix Specification v3 specifies only AF_* constants, used for
both.
Linux man socket says:
NOTE
The manifest constants used under BSD 4.* for protocol families are
PF_UNIX, PF_INET, etc., while AF_UNIX etc. are used for address fami-
lies. However, already the BSD man page promises: "The protocol family
generally is the same as the address family", and subsequent standards
use AF_* everywhere.
