refs: make sha1 output parameter of refs_resolve_ref_unsafe() optional
Allow callers of refs_resolve_ref_unsafe() to pass NULL if they don't need the resolved hash value. We already allow the same for the flags parameter. This new leniency is inherited by the various wrappers like resolve_ref_unsafe(). Signed-off-by: Rene Scharfe <l.s.r@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
