d8a30e2ad2 Net: Give the LoopbackAdapter a MAC address
Since the routing code currently interprets an all-zero MAC address as
an invalid next hop, let's give the loopback adapter an address.

94ca55cefd 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.

75ed262fe5 Kernel+ifconfig: Add an MTU value to NetworkAdapter
This defaults to 1500 for all adapters, but LoopbackAdapter increases
it to 65536 on construction.

If an IPv4 packet is larger than the MTU, we'll need to break it into
smaller fragments before transmitting it. This part is a FIXME. :^)

626e176cab Kernel: Remove IP configuration from LoopbackAdapter
This is configured in NetworkTask_main now, so there's no need to do it
here as well.

27f699ef0c AK: Rename the common integer typedefs to make it obvious what they are.
These types can be picked up by including <AK/Types.h>:

* u8, u16, u32, u64 (unsigned)
* i8, i16, i32, i64 (signed)

9e0f7acfe5 Kernel+Userland: Expose list of network adapters through /proc/netadapters.
Added a simple /bin/ifconfig program that just pretty-prints that file. :^)

c02c9880b6 AK: Add Eternal<T> and use it in various places.
This is useful for static locals that never need to be destroyed:

Thing& Thing::the()
{
    static Eternal<Thing> the;
    return the;
}

The object will be allocated in data segment memory and will never have
its destructor invoked.

718bea73b3 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/.
