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@

With uint32_t ports, we cannot sneak the port into an int anymore

Handle ports as uint32_t instead of in_port_t: OpenFlow 1.0 used 16bit ports, but later versions switched to 32bit ports (for the case that a virtual switch has more than 65535 switch ports, of course).

Branch: MAIN
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@
