Change the base_name_compare() API and the related df_name_compare()
function to take a boolean argument indicating whether the entry is a
tree or not, instead of having them call S_ISDIR(mode) on their own.
This makes use of the new "object_type" field in the "name_entry".
The API being modified here was originally added way back in
958ba6c96eb (Introduce "base_name_compare()" helper function,
2005-05-20).
