	* configure.in: Check for "struct cmsgcred" and try to access its
	members for BSD-like unices.

	* dbus/dbus-sysdeps.c (read_credentials_byte): Fold this back into
	_dbus_read_credentials_unix_socket().
	(_dbus_read_credentials_unix_socket): Use recvmsg() instead of
	read() for reading the credential byte off the unix socket.  Use
	struct cmsgcred on systems that support it.
