Subject: [PATCH] callback-job: Replace return_false() in constructors with
dedicated function
Besides being clearer, this fixes issues with GCC 15. The latter uses
C23 by default, which changes the meaning of function declarations
without parameters such as
bool return false();
Instead of "this function takes an unknown number of arguments", this
now equals (void), that is, "this function takes no arguments". So we
run into incompatible pointer type warnings all over when using such
functions. They could be cast to (void*) but this seems the cleaner
solution for this use case.

Subject: [PATCH] Cast uses of return_*(), nop() and enumerator_create_empty()
As described in the previous commit, GCC 15 uses C23 by default and that
changes the meaning of such argument-less function declarations. So
whenever we assign such a function to a pointer that expects a function
with arguments it causes an incompatible pointer type warning. We
could define dedicated functions/callbacks whenever necessary, but this
seems like the simpler approach for now (especially since most uses of
these functions have already been cast).
