logexchange: introduce helper function to get remote path name
This patch moves chunk of activepath function from hgremotenames extension
(https://bitbucket.org/seanfarley/hgremotenames/) to core. Before moving
rest of the part, there needs to be some refactoring done to schemes which
will be done as a separate series.
