We couldn't copy to_unicode, to_bytes, to_str into module_utils because
of licensing. So once created it we had two sets of functions that did
the same things but had different implementations. To remedy that, this
change removes the ansible.utils.unicode versions of those functions.
This is enough to get minimal copy module working on python3
We have t omodify dataloader's path_dwim_relative_stack and everything
that calls it to use text paths instead of byte string paths
* fixed lookup search path
added ansible_search_path var that contains the proper list and in order
removed roledir var which was only used by first_found, rest used role_path
added needle function for lookups that mirrors the action plugin one, now
both types of plugins use same pathing.
* added missing os import
* renamed as per feedback
* fixed missing rename in first_found
* also fixed first_found
* fixed import to match new error class
* fixed getattr ref
