What's the difference with original ctest here?

ctest uses a single method for renaming types, whereas we have multiple, so that gets split up.

In ctest we should rename this function rename_alias or rename_type_alias, I was thinking it handled all types for a bit

It handles all non struct and union types, we don't actually have a rename_alias method (although we can add it), since ctest doesn't use it. But rename_alias would be a different method (rename_type uses MapInput::Type, rename_alias would use MapInput::Alias).

I didn't mean to delete all of the original ctest right now :), only that you can swap a target from ctest to ctest-next rather than running both for that specific target

So I should keep test_windows but only run test_windows_next?
