Implement manual handling of objects in the library heap

[PetrPPetrov]

Something like that:

class Printer
{
public:
    void Show() {
        printer_show(this);
    }

    static void * operator new(size_t size) {
        assert(size == sizeof Printer);
        return printer_create();
    }
    
    static void operator delete(void * obj, size_t size) {
        assert(size == sizeof Printer);
        printer_destroy(obj);
    }
};
