0eea83a85e scripted-diff: rename `proxyType` to `Proxy` (Vasil Dimov)
e53a8505db net: respect -onlynet= when making outbound connections (Vasil Dimov)

Pull request description:

  Do not make outbound connections to hosts which belong to a network
  which is restricted by `-onlynet`.

  This applies to hosts that are automatically chosen to connect to and to
  anchors.

  This does not apply to hosts given to `-connect`, `-addnode`,
  `addnode` RPC, dns seeds, `-seednode`.
