b691f2df5f7d443c0c9ee056ab94aa0fc19566d5 Replace automatic bans with discouragement filter (Pieter Wuille)
Pull request description:
This patch improves performance and resource usage around IP addresses that are banned for misbehavior. They're already not actually banned since #14929, as connections from them are still allowed, but they are preferred for eviction if the inbound connection slots are full.
Stop treating these like manually banned IP ranges, and instead just keep them in a rolling Bloom filter of misbehaving nodes, which isn't persisted to disk or exposed through the ban framework. The effect remains the same: preferred for eviction, avoided for outgoing connections, and not relayed to other peers.
Also change the name of this mechanism to "discouraged" to better reflect reality.
