I seem to have made a bit of a mess when trying to rebase this to the dev branch. I Will try to fix it. |

This patch adds support for emulated local (Wi-Fi) multiplayer using libretro's netpacket API, which allows a core to send and receive arbitrary data packets across the network. In RetroArch, this can be done by using the same interface used for netplay.
Unfortunately, due to the DS's tight latency requirements for local networks, it only works for good LAN connections on a few games. I managed to play Pokémon HeartGold between my phone (connected to a WiFi AP very close by) and my PC (wired), for example. On an emulated connection, the same game worked with 8ms ping and 3% packet loss, but it could get rather laggy at times.
Thanks to @JesseTG for helping me with this.
