Subject: [PATCH] Remove dead code: extent_commit_wrapper, large_salloc,
 tcache_gc_dalloc event waits

These functions had zero callers anywhere in the codebase:
- extent_commit_wrapper: wrapper never called, _impl used directly
- large_salloc: trivial wrapper never called
- tcache_gc_dalloc_new_event_wait: no header declaration, no callers
- tcache_gc_dalloc_postponed_event_wait: no header declaration, no callers
