wrapper.c: add and use fopen_or_warn()
When fopen() returns NULL, it could be because the given path does not exist, but it could also be some other errors and the caller has to check. Add a wrapper so we don't have to repeat the same error check everywhere. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
