Konstantin Belousov 9fee0541f2 Do not call callbacks for dl_iterate_phdr(3) with the rtld bind and ... phdr locks locked. This allows to call rtld services from the callback, which is only reasonable for dlopen(path, RTLD_NOLOAD) to test existence of the library in the image, and for dlsym(). The later might still be not quite safe, due to the lazy resolution of filters. To allow dropping the locks around iteration in dl_iterate_phdr(3), we insert markers to track current position between relocks. The global objects list is converted to tailq and all iterators skip markers, globallist_next() and globallist_curr() helpers are added.
