Add the exported function write_archive_entries() to archive.c, which uses the new ability of read_tree_recursive() to pass a context pointer to its callback in order to centralize previously duplicated code. The new callback function write_archive_entry() does the work that every archiver backend needs to do: loading file contents, entering subdirectories, handling file attributes, constructing the full path of the entry. All that done, it calls the backend specific write_archive_entry_fn_t function. Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <gitster@pobox.com>
