Fix ParsedURL handling of %2F in URL paths

Browse source 
See the new extensive doxygen in `url.hh`.
This fixes fetching gitlab: flakes.

Paths are now stored as a std::vector of individual path
segments, which can themselves contain path separators '/' (%2F).
This is necessary to make the Gitlab's /projects/ API work.
