Every dlopen_xxx() helper now takes an int log_level argument. It is passed through to dlopen_many_sym_or_warn() (which in turn propagates it to dlopen_verbose() for the library-not-installed case), and is used by the fallback stub when support for the library is not compiled in to emit a "<lib> support is not compiled in." message at the caller's level. Callers pass LOG_DEBUG when gracefully degrading, or a higher level when the failure should surface, and no longer need to log redundantly at the call site. As part of this, dlopen_bpf_full() (which already took a log_level) is merged into dlopen_bpf() rather than keeping both. The static inline fallbacks used to live in the headers, which required pulling log.h in from every header that declared a dlopen_xxx(). Move them into the .c files instead: the declaration is always outside the #if HAVE_XXX block, the impl sits outside the outer #if HAVE_XXX wrap with its own internal #if HAVE_XXX/#else/#endif, and apparmor-util.c, idn-util.c, libmount-util.c and pam-util.c are now always compiled so they can host their stubs.
