 - Calling a property on the `CompletionChunk` or `CompletionString` class
   statically now leads to an error, instead of returning a `CachedProperty` object
   that is used internally. Properties are only available on instances.
+- `TranslationUnitLoadError` now contains an error code in `error_code`
+  attribute. Also, `TranslationUnit.reparse` will throw `TranslationUnitLoadError`
