After we change our magic bytes, the node may or may not send us messages such as feefilter or sendheaders, which would be rejected by _on_data.

Solve that by replacing _on_data with a noop.

Pull request description:

  Part of the deep and long net and ser work that I'm doing (and Tor v3 onion addresses support). Friend of #2359.

  Focused on the end goal of implementing the `p2p_invalid_messages` functional test which validates that invalid msg headers, msg types, oversized payloads and inventory msgs aren't accepted nor can cause a resource exhaustion. And an extra covered scenario, in `p2p_invalid_tx.py`, for the orphan pool overflow.

  Plus, to get up to the goal, had to work over the functional test framework as well.

  So.. adapted list:

  * bitcoin#9045.
  * bitcoin#13512.
  * bitcoin#13517.
  * bitcoin#13715.
  * bitcoin#13747.
  * bitcoin#14456.
  * bitcoin#14522.
  * bitcoin#14672.
  * bitcoin#14693.
  * bitcoin#14812.
  * bitcoin#15246.
  * bitcoin#15330.
  * bitcoin#15697.
  * bitcoin#16445.
  * bitcoin#17931.
  * bitcoin#17469.
  * bitcoin#18628 (only `p2p_invalid_tx.py` and `p2p_invalid_messages.py`. We don't support the other tests yet).
  * bitcoin#19177.
  * bitcoin#19264.
