pack-objects.c: fix some global variable abuse and memory leaks
To keep things well layered, sha1close() now returns the file descriptor when it doesn't close the file. An ugly cast was added to the return of write_idx_file() to avoid a warning. A proper fix will come separately. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
