Massive automated renaming of all Py_/PyObject/etc. prefixes to Ty_/TyObject/etc. This includes: - All public API types (TyObject, TyTypeObject, etc.) - All public API functions (Ty_Initialize, Ty_BuildValue, etc.) - All internal API (_Ty_ prefixes) - Reference counting macros (Ty_INCREF, Ty_DECREF, etc.) - Type flags (Ty_TPFLAGS_*) - Debug flags (Ty_DEBUG, Ty_TRACE_REFS, etc.) - All object type APIs (TyList_, TyDict_, TyUnicode_, etc.) This changes over 60,000 occurrences across 1000+ files.
