Converted: hpa_utils, ecache, extent_mmap, util, safety_check, prof_stats, peak_event, inspect, log. (src/div.c was already minimal; skipped.) One latent hermeticity bug surfaced: peak_event.h declared `extern te_base_cb_t peak_te_handler;` but didn't include thread_event_registry.h where te_base_cb_t is typedef'd. Added the include to peak_event.h. peak_event.c also needs thread_event.h directly for TE_MIN_START_WAIT. Step 6 (Option B) of the cyclical-dep cleanup, batch 2 of N.
