1. Convert Unix{Datagram,Stream}::{set_}passcred() to per-OS traits …

   These methods are the pre-stabilized API for obtaining peer credentials
   from an `AF_UNIX` socket, part of the `unix_socket_ancillary_data` feature.
   
   Their current behavior is to get/set one of the `SO_PASSCRED` (Linux),
   `LOCAL_CREDS_PERSISTENT` (FreeBSD), or `LOCAL_CREDS` (NetBSD) socket
   options. On other targets the `{set_}passcred()` methods do not exist.
   
   There are two problems with this approach:
   
   1. Having public methods only exist for certain targets isn't permitted
      in a stable `std` API.
   
   2. These options have generally similar purposes, but they are non-POSIX
      and their details can differ in subtle and surprising ways (such as
      whether they continue to be set after the next call to `recvmsg()`).
   
   Splitting into OS-specific extension traits is the preferred solution to
   both problems.
