a47df13471 [qa] Test disconnect block failure -> shutdown (Suhas Daftuar)
4433ed0f73 [validation] Crash if disconnecting a block fails (Suhas Daftuar)

Pull request description:

  If we're unable to disconnect a block during normal operation, then that is a
  failure of our local system (such as disk failure) or the chain that we are on
  (eg CVE-2018-17144), but cannot be due to failure of the (more work) chain that
  we're trying to validate.

  We should abort rather than stay on a less work chain.

  Fixes #14341.

    utACK a47df13471. Didn't bother to review the test in detail, it looked fine. Debated whether invalidateblock should ever crash the node, but *not* crashing in the case of hitting a pruned block (which is the only change here) is clearly better, even if there are other cases I'd argue we should crash in.
  ryanofsky:
    utACK a47df13471. Only change since last review is new comment.
  promag:
    ACK a47df1347, it takes awhile to quit (RPC connection timeouts) but that's unrelated - hope to fix that soon.

    ACK a47df13471
