+	Added limited support for fd relocation.  Error handling still
+	needed.
+	* src/isc_udp.c (isc_createudp): Relocate the fd.
+	* src/isc_tcp.c (isc_tcp_accept_fn): isc_createtcp will close the
+	file descriptor if it fails, so don't re-close it here.
+	isc_createtcp will also set the fd attribute of the session; don't
+	set it again.
+	(isc_createtcp): Relocate the fd.  Be careful to always close it
+	if an error occurs.
+	* src/isc_relocate.c (isc_relocate_fd): New file and function.
+	This is still a dummy implementation.
+	* src/isc_master.c (isc_initialize): Expect master config version
+	1006 and session config 1002.  Handle fd_relocate.
+	* src/isc.h (IscSessionConfig): Added fd_relocate.
+	* src/intern.h (isc_relocate_fd): New function.
+	* src/Makefile.am (libisc_a_SOURCES): Added isc_relocate.c.
