Log Message:
Implement TODO item to unwind target mounts on  completion:
  * Add mount_with_unwind() that adds mountpoint to a LIFO queue
    of  mountpoints to undo on error.   Use in target_mount().
  * Add unwind_mounts() which traverses the LIFO queue and unmounts
    filesystems, silently ignoring errors.
  * create toplevel() function which displays banner message and
    calls unwind_mounts().
  * change toplevel menu to call toplevel() instead of inline banner.

Where to do unwinds needs more thought.  Perhaps we should only unwind
if an upgrade or install appears unsuccessful, so after a successful
install, the target is mounted (e.g., for upgrading /etc/rc.conf).
