o Back out portions of 1.50 and 1.47, eliminating sonewconn3() and

  always deriving the credential for a newly accepted connection from
  the listen socket.  Previously, the selection of the credential
  depended on the protocol: UNIX domain sockets would use the
  connecting process's credential, and protocols supporting a creation
  of the socket before the receiving end called accept() would use
  the listening socket.  After this change, it is always the listening
  credential.
