Qt wallets display information to users about the broadcast state of transactions, without truly knowing the actual state. The fact that a peer has requested details for a transaction does not mean it was accepted to their mempool or relayed to any other peers and miners, because the only way to test if the transaction can be accepted is by requesting and processing it. We remove the "offline" and "maturity warning" statuses, which saves large wallets memory and processing time. Backported from: beef7ec4 Original author: Matt Corallo <git@bluematt.me>
