  passfd: speed up configure and drop unused code
  
  Ultimately, it would be nice to provide a sendmsg and recvmsg module,
  and have those provide a replacement struct msghdr and silently
  convert msg_accrights into the replacement struct's msg_control, when
  targeting older BSD.  But until that point in time, this is a nice
  cleanup.
  
  SCM_RIGHTS really only works on Unix sockets; however, there is
  nothing in passfd.c that needs to be hard-coded to this (rather,
  the hard-coding of the address family is done externally when
  the socket or socketpair is created).
  
  * m4/afunix.m4 (gl_SOCKET_AFUNIX): Rename...
  * m4/passfd.m4 (gl_PASSFD): ...to something more fitting of
  its use.  Drop test for setting unused HAVE_UNIXSOCKET_SCM_RIGHTS.
  Instead of probing at configure for unix_scm_rights_bsd44_way,
  instead probe for CMSG_FIRSTHDR at compile time.  Simplify BSD 4.3
  check to a struct member probe.
  * lib/passfd.c (includes): Nothing here requires <sys/un.h>.
  (sendfd, recvfd): Update preprocessor checks.
  * modules/passfd (Files): Reflect rename, and drop unused file.
  (Depends-on): Drop unused dependency.
