This commit affects `id_sort_by_name()` and `check_for_dupid()` helper: * Add a new parameter, `ID *id_sorting_hint`, to `id_sort_by_name()`, and when non-NULL, check if we can insert `id` immediately before or after it. This can dramatically reduce time spent in that function. * Use loop over whole list in `check_for_dupid()` to also define the likely ID pointer that will be neighbor with our new one. This gives another decent speedup to all massive addition cases: | Number and type of names of IDs | old code | new code | speed improvement | | -------------------------------- | -------- | -------- | ----------------- | | 40K, mixed (14k rand, 26k const) | 39s | 33s | 18% | | 40K, fully random | 51s | 42s | 21% | | 40K, fully constant | 40s | 34s | 18% | Combined with the previous commits, this makes massive addition of IDs more than twice as fast as previously.
