Add a lockfile function to append to a file
This takes care of copying the original contents into the replacement file after the lock is held, so that concurrent additions can't miss each other's changes. [jc: munged to drop mmap in favor of copy_file.] Signed-off-by: Daniel Barkalow <barkalow@iabervon.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
