Meta: Add license header to source files As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header.

Kernel: Add a LoopbackAdapter for talking to yourself via 127.0.0.1. Choosing adapter for transmit is done by adapter_for_route_to(IPv4Address). This is just hard-coded logic right now but can be expanded to support a proper routing table. Also start moving kernel networking code into Kernel/Net/.

Kernel: Move block condition evaluation out of the Scheduler This makes the Scheduler a lot leaner by not having to evaluate block conditions every time it is invoked. Instead evaluate them as the states change, and unblock threads at that point. This also implements some more waitid/waitpid/wait features and behavior. For example, WUNTRACED and WNOWAIT are now supported. And wait will now not return EINTR when SIGCHLD is delivered at the same time.

Net: Make NetworkAdapter reference-counted The idea behind WeakPtr<NetworkAdapter> was to support hot-pluggable network adapters, but on closer thought, that's super impractical so let's not go down that road.

Kernel: Add simple ARP routing layer This replaces the previous placeholder routing layer with a real one! It's still very primitive, doesn't deal with things like timeouts very well, and will probably need several more iterations to support more normal networking things. I haven't confirmed that this works with anything other than the QEMU user networking layer, but I suspect that's what nearly everybody is using at this point, so that's the important target to keep working.

Kernel: Add the SO_BINDTODEVICE socket option This patch adds a way for a socket to ask to be routed through a specific interface. Currently, this option only applies to sending, however, it should also apply to receiving...somehow :^)
