• Move application layer data from net to net_processing:

  • #21186 is the next PR in the series - Move addr data into net_processing
• Clean up addrman:
  • #20233 makes consistency checks a runtime option, so they can be used in unit/functional/fuzz tests (currently WIP)
• Review and help AJ's general cleanups #20758
• Review and help Carl's de-globalize chainstate manager #20158 (this is mostly in validation but touches the net_processing-validation interface a lot).
