Carlos Martín Nieto c76c3f0195 Start implementing remotes with CFFI
This moves enough code into python with CFFI to pass the test_remotes
unit tests. There is no credentials support yet.

There is a small change in the return value of Remote.fetch() in that we
now return a TransferProgress object instead of extracting a few values
into a dictionary.
