sin-ack 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.
