From: Elijah Newren <newren@xxxxxxxxx> None of base_name_compare(), df_name_compare(), or name_compare() depended upon a cache_entry or index_state in any way. By moving these functions to tree.h, half a dozen other files can stop depending upon cache.h (though that change will be made in a later commit).
