`lib/queue.h` implements a basic queue. `event/queue.c` implements a specialized data structure on top of lib/queue.h; it is not a "normal" queue. Rename the specialized multi-level queue implemented in event/queue.c to "multiqueue", to avoid confusion when reading the code. Before this change one can eventually notice that "macros (uppercase symbols) are for the normal queue, lowercase operations are for the multi-level queue", but that is unnecessary friction for new developers (or existing developers just visiting this part of the codebase).
