---------------------------------------------------------------
Updated the PR to also include viewfs support to the c++ fs. Please review.
I kept the changes in Python `resolve_filesystem_and_path` as this is directly
usable and make the new Fs compliant to the old API/update doc, .. may probably
take some time.
