FILE REMOVED
Retire switchd and switchctl. While interesting they never managed to really get into a usable state. The OpenFlow API is mostly superseeded by P4 and so this is a bit of a dead end. OK akoshibe@ yasuoka@ deraadt@ kn@ patrick@ sthen@

switchd(8) will sometimes not save a copy of a packet needing forwarding even when a switch(4) instance requires it to supply it. Cases where this can happen are: if the copy of the packet recieved from the switch is too short (source/destination pairs can't be recovered), is non-unicast, or when switchd has to fall back to flooding traffic. Factor out the check for short packets, stopping before forwarding decisions are made if the full packet is needed by the switch. Set the packet buffer early for cases where it is needed otherwise. Also replace a few bzero's with memset's. Diff based on one by guenther@ OK phessler@

Make switchd(8) ignore PACKET_INs generated from looped traffic. Currently, it responds to these messages with an invalid PACKET_OUT onto OFP*_PORT_ANY, resulting in the switch responding with an error, causing switchd to disconnect the switch. OK phessler@ claudio@

Implement socket server code that properly handles async I/O, partial messages, multiple messages per buffer and important things like connection limits and file descriptor accounting. It works with TCP connections as well as switch(4). The ofrelay.c part replaces networking that was in ofp.c and will soon handle all socket connections of switchd. It is called "ofrelay" because it will be used as client, server, and forwarder. OK rzalamena@

OpenFlow PACKET_IN can send truncated packets; this only makes sense if the switch buffers packets, otherwise we might end up forwarding truncated packets to the network with the PACKET_OUT response. So, for now, only close the connection if the packet is not buffered by the switch but truncated. OK rzalamena@

Import switchd(8), a basic WIP OpenFlow implementation for OpenBSD. switchd consists of two parts: 1. switchd(8) and switchctl(8), an OpenFlow controller or "vswitch". 2. switch(4), an OpenFlow-aware kernel "bridge". This the 1st part, the driver will be imported later. The code will remain disabled for a while, but it helps development to have it in the tree. switchd currently supports partial OpenFlow 1.0, but the goal is to use OpenFlow 1.3.5 instead (switch(4) already does 1.3.5). For more background information see: http://www.openbsd.org/papers/bsdcan2016-switchd.pdf https://youtu.be/Cuo0qT-lqig With help from yasuoka@ goda@ Import discussed with deraadt@
