Description:
------------
INIT_CLASS_ENTRY macro should not use sizeof

e.g. such usage is valid:
INIT_CLASS_ENTRY(ce, "MyCustomClass", NULL);
as compiler uses such directives:
INIT_OVERLOADED_CLASS_ENTRY   (class_container, class_name,                       functions, NULL,        NULL,             NULL)
INIT_OVERLOADED_CLASS_ENTRY_EX(class_container, class_name, sizeof(class_name)-1, functions, handle_fcall, handle_propget, handle_propset, NULL, NULL)

but if INIT_CLASS_ENTRY is used in the function like:
void InitClass(const char *class_name) {
   zend_class_entry ce;
  INIT_CLASS_ENTRY(ce, class_name, NULL);

will fail due the:
INIT_OVERLOADED_CLASS_ENTRY_EX define implementation:
sizeof(class_name)-1

maybe strlen (run-time) 
should be used to allow INIT_CLASS_ENTRY macro more general usage.
