[PATCH 06/18] send-pack: refactor decision to send update per ref

[Junio C Hamano <gitster@pobox.com>]

A new helper function ref_update_to_be_sent() decides for each ref
if the update is to be sent based on the status previously set by
set_ref_status_for_push() and also if this is a mirrored push.
