Currently, when the argument of copyObject() is const-qualified, the return type is also, because the use of typeof carries over all the qualifiers. This is incorrect, since the point of copyObject() is to make a copy to mutate. But apparently no code ran into it. The new implementation uses typeof_unqual, which drops the qualifiers, making this work correctly. typeof_unqual is standardized in C23, but all recent versions of all the usual compilers support it even in non-C23 mode, at least as __typeof_unqual__. We add a configure/meson test for typeof_unqual and __typeof_unqual__ and use it if it's available, else we use the existing fallback of just returning void *.
