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
* These can still race when multiple ansible processes are created at
the same time.
* Reverse order of expanduser and expandvars in unfrakpath(). So that
tildes in environment variables will be handled.
Required some rewiring in inventory code to make sure we're using
the DataLoader class for some data file operations, which makes mocking
them much easier.
Also identified two corner cases not currently handled by the code, related
to inventory variable sources and which one "wins". Also noticed we weren't
properly merging variables from multiple group/host_var file locations
(inventory directory vs. playbook directory locations) so fixed as well.
