b19c1a2e4f [MP] New default multiplayer_peer acting as server.
Adds a OfflineMultiplayerPeer class which behaves like a server with no
connected peers.

Use OfflineMultiplayerPeer as default for SceneMultiplayer.

This means that the SceneTree will act as the multiplayer authority by
default.
Calls to is_server will return true, and calls to get_unique_id will
return TARGET_PEER_SERVER.

fdc4e73a2c [MP] RPC visibility.
Implemented using MultiplayerSynchronizers.

If you didn't use the synchronizer visibility features, nothing changes.

If you were using visibility, RPCs to broadcast should now behave as
expected in most configurations (i.e. by sending the RPC to _visible_
peers).

If you want to limit the visibility of RPCs for a node, add a
synchronizer for it, and configure the visibility via
"set_visibility_for" or by adding a visibility filter.

92ed27d8f6 [MP] Improve network profiler.
Fix RPC profiler and add average RPC size.

Improve bandwidth debugger to account for all multiplayer traffic
(excluding the lower level peer transformations).

9773803e4e [MP] Add optional authentication to SceneMultiplayer.
Add few methods to allow peers to exchange authentication information.

- `set_auth_callback(callback)`: Enable the authentication features.
  The callback is a `Callable` that accepts an `int` (the peer ID), and
  a `PackedByteArray` of data.
- The `peer_authenticating(id)` signal will be emitted instead of
  `peer_connected` when a new peer connects.
- Use `send_auth(id: int, data: PackedByteArray)` to exchange data.
- Call `complete_auth(id: int)` when the authentication process is
  complete and you expect to start receiving game data.
- The `peer_connected` signal will be emitted as soon as both parties
  complete the authentication.
- Use `disconnect_peer(id)` to disconnect a connected peer.
- If the `peer_connected` signal didn't fire for that peer (i.e. it was
  still in the authentication phase), the `peer_auth_failed` signal will
  be emitted instead of `peer_disconnected`.

7536d15fe3 [MP] Let MultiplayerAPI handle packet relaying and peer signaling.
MultiplayerPeer changes:

- Adds is_server_relay_supported virtual method

Informs the upper MultiplayerAPI layer if it can signal peers connected
to the server to other clients, and perform packet relaying among them.

- Adds get_packet_channel and get_packet_mode virtual methods

Allows the MultiplayerAPI to retrieve the channel and transfer modes to
use when relaying the last received packet.

SceneMultiplayerPeer changes:

- Implement peer signaling and packet relaying when the MultiplayerPeer
  advertise they are supported.

ENet, WebRTC, WebSocket changes:

- Removed custom code for relaying from WebSocket and ENet, and let it
  be handled by the upper layer.
- Update WebRTC to split create_client, create_server, and create_mesh,
  with the latter behaving like the old initialize with
  "server_compatibility = false", and the first two supporting the upper
  layer relaying protocol.
