Pull request description:

  This PR contains the first part of #10882 :

  - if a key from the keypool is used, mark all keys up to that key as used, and then try to top up the keypool
  - top up the keypool on startup

  Notably, it does not stop the node or prevent the best block from advancing if the keypool drops below a threshold (which means that transactions may be missed and funds lost if restoring from an old HD wallet backup).
