[PATCH v3 00/12] Reroll of the remote-vcs-helper series

My helper is fully functional now so I think after one more round
this will be ready for next (we need some more documentation).

Daniel Barkalow (8):
      Fix memory leak in helper method for disconnect
      Allow programs to not depend on remotes having urls
      Use a function to determine whether a remote is valid
      Allow fetch to modify refs
      Add a config option for remotes to specify a foreign vcs
      Add support for "import" helper command
      Allow helper to map private ref names into normal names
      Allow helpers to report in "list" command that the ref is unchanged

Johan Herland (1):
      Basic build infrastructure for Python scripts

Johannes Schindelin (1):
      Allow specifying the remote helper in the url

Sverre Rabbelier (2):
      Allow helpers to request the path to the .git directory
      Add Python support library for remote helpers
