The functions ecore_x_window_prop_card32_list_get, ecore_x_window_prop_xid_get, and...

The functions ecore_x_window_prop_card32_list_get, ecore_x_window_prop_xid_get, and ecore_x_window_prop_xid_list_get were buggy.

The original intention was that if the property is absent or not of extected type (or invalid window) they should return -1, otherwise they should return the number of elements in the property, 0 if none.

Unfortunately they all returned 0 if the property does not exist. Also, ecore_x_window_prop_xid_list_get retuned 0 if the property exists, has no elements, but has wrong type (should be -1).

These issues should be fixed now but this may cause problems in any code that relied on the incorrect behavior.
