Subject: Drop upgrade-cancel callback registration for a generic "resumeable"

Instead of passing a StartShutdown reference all the way up from
txdb, give ShowProgress a "resumeable" boolean, which is used to
inform the user if the action will be resumed, but cancel is always
allowed by just calling StartShutdown().
