Description: Python built with "configure --with-trace-refs" (tracing references) is now ABI compatible with Python release build and debug build. Moreover, it now also supports the Limited API. Change Py_TRACE_REFS build: Remove _PyObject_EXTRA_INIT macro. The PyObject structure no longer has two extra members (_ob_prev and _ob_next). Use a hash table (_Py_hashtable_t) to trace references (all objects): PyInterpreterState.object_state.refchain. Py_TRACE_REFS build is now ABI compatible with release build and debug build. Limited C API extensions can now be built with Py_TRACE_REFS: xxlimited, xxlimited_35, _testclinic_limited. No longer rename PyModule_Create2() and PyModule_FromDefAndSpec2() functions to PyModule_Create2TraceRefs() and PyModule_FromDefAndSpec2TraceRefs(). _Py_PrintReferenceAddresses() is now called before finalize_interp_delete() which deletes the refchain hash table. Test changes for Py_TRACE_REFS: Add test.support.Py_TRACE_REFS constant. Add test_sys.test_getobjects() to test sys.getobjects() function. test_exceptions skips test_recursion_normalizing_with_no_memory() and test_memory_error_in_PyErr_PrintEx() if Python is built with Py_TRACE_REFS. test_repl skips test_no_memory(). test_capi skisp test_set_nomemory().
