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.
Previously, split_args() was not taking print/block/comment depth into account
when splitting things, meaning that if there was a quote character inside an
un-quoted variable (ie. {{ foo | some_filter(' ') }}), it was incorrectly
splitting on the quotes instead of continuing to append to the previous param.
