BKE_main_id_tag_/BKE_main_id_flag_ were horrible naming now that we split those into flags (for presistent one) and tags (for runtime ones). Got rid of previous 'tag_' functions behavior (those who were dedicated shortcuts to set/clear LIB_TAG_DOIT), so now '_tag_' functions affect tags, and '_flag_' functions affect flags.
