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.
