db2ede9427 Net: Short-circuit routing to the IPv4 address of a local adapter
This makes it possible to open http://localhost:8000/ in Browser. :^)

80703ef7d9 WebServer: Send the HTTP response headers in a single packet
This makes it easier to observe the protocol in packet logs.

6c752c15a2 WebServer: Implement a very basic HTTP server :^)
This server listens on port 8000 and serves HTML files from /www.
It's very simple and quite naive, but I think we can start here and
build our way to something pretty neat.

Work towards #792.

271bc4b2f2 Net: When routing to loopback, use the loopback adapter's MAC address
Otherwise the routing decision gets interpreted as "host unreachable."

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.

80b1af2352 AK: Make StringBuilder::to_string() non-destructive
This was an artifact of an earlier design of StringBuilder where I had
attempted to preserve the same allocation from build to final String.

3a7e49fe07 LibCore: Allow constructing a Core::HttpRequest from a raw HTTP request
This patch adds a very simple HTTP request parser that can be useful
for implementing say.. a web server. :^)

fc85d17322 TelnetServer: Protect the Client object during drain_socket()
If parsing a command causes us to disconnect the client, we have to
defer deletion of the Client object until we're done with the socket.

228a1e9099 IPv4: Basic implementation of TCP socket shutdown
We can now participate in the TCP connection closing handshake. :^)
This implementation is definitely not complete and needs to handle a
bunch of other cases. But it's a huge improvement over not being able
to close connections at all.

Note that we hold on to pending-close sockets indefinitely, until they
are moved into the Closed state. This should also have a timeout but
that's still a FIXME. :^)

Fixes #428.

8325662186 more: Read keystrokes from stdout instead of trying to re-open it
If we're running more on a TTY that we don't have filesystem access to,
we can't rely on open(ttyname(STDOUT_FILENO)). Since all the stdio fd's
are opened read/write anyway, we can just read from stdout, even if it
feels a bit weird. :^)

1037a1d2ba IPv4: Don't ACK empty TCP packets

48f13f2a81 IPv4: Split IPv4Socket::recvfrom() into packet/byte buffered functions
This code was really hard to follow since it handles two separate modes
of buffering the data.

00d8ec3ead Kernel: The inode fault handler should grab the VMObject lock earlier
It doesn't look healthy to create raw references into an array before
a temporary unlock. In fact, that temporary unlock looks generally
unhealthy, but it's a different problem.

a9d7902bb7 x86: Simplify region unmapping a bit
Add PageTableEntry::clear() to zero out a whole PTE, and use that for
unmapping instead of clearing individual fields.

7291370478 Kernel: Make File::truncate() take a u64
No point in taking a signed type here. We validate at the syscall layer
and then pass around a u64 from then on.

42d41fdf94 Kernel: Simplify FS::create_inode() a little bit
Return a KResultOr<NonnullRefPtr<Inode>> instead of returning errors in
an out-parameter.

2f82d4fb31 Kernel: Add KResultOr<T>::result()
This is just a handy way to get either an error or a KSuccess, even if
there is a T present.

745ea2a0ef AK: Add JsonObjectSerializer::add(key, bool) overload
Without this, bools will get implicitly converted to integers, which is
usually not what we want.

8731682d0e Kernel: Simplify FS::create_directory() a little bit
None of the clients of this function actually used the returned Inode,
so it can simply return a KResult instead.

2b0b7cc5a4 Net: Add a basic sys$shutdown() implementation
Calling shutdown prevents further reads and/or writes on a socket.
We should do a few more things based on the type of socket, but this
initial implementation just puts the basic mechanism in place.

Work towards #428.

a3f39fe789 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.

There's also no sys$spawn() anymore.

d04fcccc90 Kernel: Truncate addresses stored by getsockname() and getpeername()
If there's not enough space in the output buffer for the whole sockaddr
we now simply truncate the address instead of returning EINVAL.

This patch also makes getpeername() actually return the peer address
rather than the local address.. :^)

bb8e65be41 LibGUI+HackStudio: Move syntax highlighting from HackStudio to LibGUI
This patch introduces the GUI::SyntaxHighlighter class, which can be
attached to a GUI::TextEditor to provide syntax highlighting.

The C++ syntax highlighting from HackStudio becomes a new class called
GUI::CppSyntaxHighlighter. This will make it possible to get C++ syntax
highlighting in any app that uses a GUI::TextEditor. :^)

Sidenote: It does feel a bit weird having a C++ lexer in a GUI toolkit
library, and we'll probably end up moving this out to a separate place
as this functionality grows larger.

6bda3bd8da SystemServer: Limit service restarts
SystemServer will now track the number of restart attempts and the
run time of a service, and will also pay attention to its exit code.
If a service exits unsuccessfully and too quickly (in less than a
second), SystemServer will only attempt to restart it twice.

This means that if WindowServer crashes on startup, we will now see
just a few copies of the crash instead of the quickly scrolling log
flashing with colors :^)

960df8a62a WindowServer: Don't try to load unspecified icons
Some apps (looking at you, VisualBuilder) don't specify an icon
in their .af file, so WindowServer was trying to open an empty path.
That made it print a perror message to the log each time. Let's not
do that ^)
