view: do not store a pointer to NautilusWindow

Instead, use nautilus_view_get_ui_manager() and
nautilus_view_get_window(), and turn the checks on window != NULL to
slot != NULL.
This is needed in preparation for detachable tabs; since the window for
a given slot might change underway then, avoid staying out of sync by
not storing a pointer to the window.
pathbar: clear buttons directly when file is gone

Instead of having the code in nautilus-window-manage-views clear the
pathbar, since it receives the same signal, handle it internally. This
should make code more robust.

monitor: watch for removal of non-native mounts on GVolumeMonitor

Nowadays, we rely on G_FILE_MONITOR_EVENT_UNMOUNTED to be emitted when a
mount disappears, since we already monitor the directory, in order to
switch the view to a different location.
Since non-native mounts very likely won't have file monitoring though,
we're not going to receive such events in that case, and fail to
redirect the view as a consequence.
This patch fixes it by listening to the mount-removed signal on
GVolumeMonitor when a monitor is requested for a non-native mount, and
emulating a file removal in that case.

Detect whem a unmount happans and a subfolder of the mount is dispalyed.

The previous solution does a GMount pointer compare. But this was not working in any case. This patche fixes it by compareing the mount root with the current location.
This fixes a regression since 0852847e2613dbcebb4ed7f58e5b2aee3aa86a9
