* mount.c (mountee_node): New variable.
(mountee_root): Likewise.
(mountee_started): Likewise.
(start_mountee): New function (based on node_set_translator
in nsmux).
(setup_unionmount): New function.
* mount.h (mountee_root): New variable.
(mountee_started): Likewise.
(start_mountee): New function.
(setup_unionmount): New function.
