This has several significant changes to the networking stack. * Significant refactoring of the TCP state machine. Right now it's probably more fragile than it used to be, but handles quite a lot more of the handshake process. * `TCPSocket` holds a `NetworkAdapter*`, assigned during `connect()` or `bind()`, whichever comes first. * `listen()` is now virtual in `Socket` and intended to be implemented in its child classes * `listen()` no longer works without `bind()` - this is a bit of a regression, but listening sockets didn't work at all before, so it's not possible to observe the regression. * A file is exposed at `/proc/net_tcp`, which is a JSON document listing the current TCP sockets with a bit of metadata. * There's an `ETHERNET_VERY_DEBUG` flag for dumping packet's content out to `kprintf`. It is, indeed, _very debug_.
