auto merge of #11186 : alexcrichton/rust/native-udp, r=brson

I personally do not have huge amounts of experience in this area, so there's likely a thing or two wrong around the edges. I tried to just copy what libuv is doing as closely as possible with a few tweaks in a few places, but all of the `std::io::net::udp` tests are now run in both native and green settings so the published functionality is all being tested.
