Kernel: Add SocketHandle helper class that wraps locked sockets.
...
This allows us to have a comfy IPv4Socket::from_tcp_port() API that returns
a socket that's locked and safe to access. No need to worry about locking
at the client site.

IPv4: Last burst of TCP hacking for today.
...
Connecting to a test server and exchanging data back and forth works.

IPv4: More work on the TCP implementation.
...
Reading from the peer now kinda works. Something still going wrong with
sending packets but it's getting closer.

We don't actually have TCP support yet, but we'll get there soon. :^)

I'm now able to connect to a simple UDP server on my host machine and
exchange some data. Very cool! :^)

Add support for socket send/receive timeouts.
...
Only the receive timeout is hooked up yet. You can change the timeout by
calling setsockopt(..., SOL_SOCKET, SO_RCVTIMEO, ...).
Use this mechanism to make /bin/ping report timeouts.

More work on IPv4 sockets and /bin/ping.
...
It's now actually possible to ping other hosts on the network! :^)
I've switched the "run" script over to starting QEMU with user networking
since that works better for my testing needs right now.

All ICMP sockets now receive all ICMP packets. All this buffering is gonna
need some limits and such.
