Consolidate all hooks structures into a single one. There are no static dlopen ABI concerns because glibc 2.34 already comes with substantial ABI-incompatible changes in this area. (Static dlopen requires the exact same dynamic glibc version that was used for static linking.) The new approach uses a pointer to the hooks structure into _rtld_global_ro and initalizes it in __rtld_static_init. This avoids a back-and-forth with various callback functions.
