166a905951 Userland: Properly populate GENERATED_SOURCES
We previously put the generated headers in SOURCES, which did not mark
them as GENERATED (and did not produce a proper dependency).
This commit moves all generated headers into GENERATED_SOURCES, and
removes useless header SOURCES.

3f3f45580a Everywhere: Add sv suffix to strings relying on StringView(char const*)
Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).

No functional changes.

2b82c83ceb LookupServer: Use _POSIX_HOST_NAME_MAX instead of HOST_NAME_MAX
HOST_NAME_MAX is not defined on the BSDs, including macOS. Use
_POSIX_HOST_NAME_MAX instead, which is defined on all the platforms.

579eb7cf41 LookupServer: Use designated initializers for sockaddr_in
At least macOS has a non-standard sin_len field at the front of
the struct that Linux and Serenity do not. On BSDs, the
sin_len field must be initialized to the size of the structure.

7ceeb74535 AK: Use an enum instead of a bool for String::replace(all_occurences)
This commit has no behavior changes.

In particular, this does not fix any of the wrong uses of the previous
default parameter (which used to be 'false', meaning "only replace the
first occurence in the string"). It simply replaces the default uses by
String::replace(..., ReplaceMode::FirstOnly), leaving them incorrect.

888d8e53a3 LookupServer: Try other available DNS nameservers on network errors
We were accidentally short-circuting DNS lookup on network errors when
contacting the first DNS server, instead of trying the other available
options.

3b1e063d30 LibCore+Everywhere: Make Core::Stream::read() return Bytes
A mistake I've repeatedly made is along these lines:
```c++
auto nread = TRY(source_file->read(buffer));
TRY(destination_file->write(buffer));
```

It's a little clunky to have to create a Bytes or StringView from the
buffer's data pointer and the nread, and easy to forget and just use
the buffer. So, this patch changes the read() function to return a
Bytes of the data that were just read.

The other read_foo() methods will be modified in the same way in
subsequent commits.

Fixes #13687

46710d9efa LookupServer: Use case-insensitive comparison for domain names
Some ISPs may MITM DNS requests coming from clients, changing the case
of domain name in response. LookupServer will refuse responses from
any DNS server in that case. This commit changes the behaviour to
perform a case-insensitive equality check.

3a71748e5d Userland: Rename IPC ClientConnection => ConnectionFromClient
This was done with CLion's automatic rename feature and with:
find . -name ClientConnection.h
    | rename 's/ClientConnection\.h/ConnectionFromClient.h/'

find . -name ClientConnection.cpp
    | rename 's/ClientConnection\.cpp/ConnectionFromClient.cpp/'

8260135d4d LibCore+Everywhere: Return ErrorOr from ConfigFile factory methods
I've attempted to handle the errors gracefully where it was clear how to
do so, and simple, but a lot of this was just adding
`release_value_but_fixme_should_propagate_errors()` in places.

2e1bbcb0fa LibCore+LibIPC+Everywhere: Return Stream::LocalSocket from LocalServer
This change unfortunately cannot be atomically made without a single
commit changing everything.

Most of the important changes are in LibIPC/Connection.cpp,
LibIPC/ServerConnection.cpp and LibCore/LocalServer.cpp.

The notable changes are:
- IPCCompiler now generates the decode and decode_message functions such
  that they take a Core::Stream::LocalSocket instead of the socket fd.
- IPC::Decoder now uses the receive_fd method of LocalSocket instead of
  doing system calls directly on the fd.
- IPC::ConnectionBase and related classes now use the Stream API
  functions.
- IPC::ServerConnection no longer constructs the socket itself; instead,
  a convenience macro, IPC_CLIENT_CONNECTION, is used in place of
  C_OBJECT and will generate a static try_create factory function for
  the ServerConnection subclass. The subclass is now responsible for
  passing the socket constructed in this function to its
  ServerConnection base; the socket is passed as the first argument to
  the constructor (as a NonnullOwnPtr<Core::Stream::LocalServer>) before
  any other arguments.
- The functionality regarding taking over sockets from SystemServer has
  been moved to LibIPC/SystemServerTakeover.cpp. The Core::LocalSocket
  implementation of this functionality hasn't been deleted due to my
  intention of removing this class in the near future and to reduce
  noise on this (already quite noisy) PR.

6d0f504822 LibIPC: Add IPC::MultiServer convenience class
This encapsulates what our multi-client IPC servers typically do on
startup:

    1. Create a Core::LocalServer
    2. Take over a listening socket file descriptor from SystemServer
    3. Set up an accept handler for incoming connections

IPC::MultiServer does all this for you! All you have to do is provide
the relevant client connection type as a template argument.

92f8514a85 Services: Cast unused IPC::new_client_connection() results to void
These ones all manage their storage internally, whereas the WebContent
and ImageDecoder ones require the caller to manage their lifetime. This
distinction is not obvious to the user without looking through the code,
so an API that makes this clearer would be nice.

fe00393941 LibCore: Change Core::LocalServer::on_ready_to_accept => on_accept
Everyone used this hook in the same way: immediately accept() on the
socket and then do something with the newly accepted fd.

This patch simplifies the hook by having LocalServer do the accepting
automatically.

This adds a FileWatcher to the LookupServer which watches '/etc/hosts'
for changes during runtime and reloads its contents. If the file is
deleted, m_etc_hosts will be cleared.

Since we now need to access '/etc/hosts' later during runtime, it needs
to be unveiled with read permissions.

It also adds a few error checks for invalid entries in /etc/hosts,
trims away leading and trailing whitespace from lines and tries to use
StringView over String.
