This PR adds a high priority broadcast routine in the v1 reactor. By implementing this as a separate routine that essentially acts as a sidecar, we attempt to avoid any invasive changes to the original mempool that may have unintended consequences that require further testing.
This creates a separate broadcast routine with a separate P2P channel that periodically every
mempoolPriorityInterval
, sorts the transactions, reapsmempoolPriorityBroadcastMaxBytes
, and triggers a sidecar broadcast routine in all peers.Addresses #1069
