  config: borrow refcounted references
  
  This changes the get_entry() method to return a refcounted version of
  the config entry, which you have to free when you're done.
  
  This allows us to avoid freeing the memory in which the entry is stored
  on a refresh, which may happen at any time for a live config.
  
  For this reason, get_string() has been forbidden on live configs and a
  new function get_string_buf() has been added, which stores the string in
  a git_buf which the user then owns.
  
  The functions which parse the string value takea advantage of the
  borrowing to parse safely and then release the entry.
