  Slim down git_transport Remove the unused repo and private pointers and make the direction a flag, as it can only have two states. Change the connect signature to use an int instead of git_net_direction and remove that enum. Signed-off-by: Carlos Martín Nieto <carlos@cmartin.tk>

  /*
   * A day in the life of a network operation
   * ========================================
   *
   * The library gets told to ls-remote/push/fetch on/to/from some
   * remote. We look at the URL of the remote and fill the function
   * table with whatever is appropriate (the remote may be git over git,
   * ssh or http(s). It may even be an hg or svn repository, the library
   * at this level doesn't care, it just calls the helpers.
   *
   * The first call is to ->connect() which connects to the remote,
   * making use of the direction if necessary. This function must also
   * store the remote heads and any other information it needs.
   *
   * If we just want to execute ls-remote, ->ls() gets
   * called. Otherwise, the have/want/need list needs to be built via
   * ->wanthaveneed(). We can then ->push() or ->pull(). When we're
   * done, we call ->close() to close the connection. ->free() takes
   * care of freeing all the resources.
