Merge bitcoin#9254: [depends] ZeroMQ 4.2.2

126999d depends: fix zmq build with mingw < 4.0 (Cory Fields)
387879d [depends] ZeroMQ 4.2.2 (fanquake)

Pull request description:

  Update depends ZeroMQ to 4.2.2, the release notes are available [here](https://github.com/zeromq/libzmq/releases).

  We can drop both patches, as they have both been merged upstream (they actually had been for some time but just hadn't yet made it into a release).

  `--without-documentation` is deprecated and has been replaced with `--without-docs`.
  `--disable-perf` disables building performance measuring tools, which are enabled by default, see the libzmq [configure.ac](https://github.com/zeromq/libzmq/blob/master/configure.ac#L367).
  Updated dependencies.md.
  `--disable-curve-keygen` disable building the curve key generation tool. See [here](https://github.com/zeromq/libzmq/blob/master/configure.ac#L405).

  Can someone on windows test that this is still working correctly. Maybe @achow101 ?
