Fix C23 compiler warning The approach of declaring a function pointer with an empty argument list and hoping that the compiler will not complain about casting it to another type no longer works with C23, because foo() is now equivalent to foo(void).
We don't need to do this here. With a few struct forward declarations we can supply a correct argument list without having to pull in another header file. (This is the only new warning with C23. Together with the previous fix a67a49648d9, this makes the whole code compile cleanly under C23.)
