notes: refactor display notes default handling
This is in preparation for more notes-related revision command-line options. The "suppress_default_notes" option is renamed to "use_default_notes", and is now a tri-state with values less than one indicating "not set". If the value is "not set", then we show default refs if and only if no other refs were given. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
