One Copyright Update to rule them all As many open source projects have started doing it, we're removing the current year from the copyright notice, so that we don't need to bump it every year. It seems like only the first year of publication is technically relevant for copyright notices, and even that seems to be something that many companies stopped listing altogether (in a version controlled codebase, the commits are a much better source of date of publication than a hardcoded copyright statement). We also now list Godot Engine contributors first as we're collectively the current maintainers of the project, and we clarify that the "exclusive" copyright of the co-founders covers the timespan before opensourcing (their further contributions are included as part of Godot Engine contributors). Also fixed "cf." Frenchism - it's meant as "refer to / see".

#ifndef WEBSOCKET_PEER_H
#define WEBSOCKET_PEER_H
Add websocket module. Webassembly is client-only for obvious reasons. Other platforms support both client and server using libwebsockets.

[WebSocket] Refactor websocket module. This commit is a huge refactor of the websocket module. The module is really old, and some design choices had to be re-evaluated. The WebSocketClient and WebSocketServer classes are now gone, and WebSocketPeer can act as either client or server. The WebSocketMultiplayerPeer class is no longer abstract, and implements the Multiplayer API on top of the lower level WebSocketPeer. WebSocketPeer is now a "raw" peer, like StreamPeerTCP and StreamPeerTLS, so it emits no signal, and just needs polling to update its internal state. To use it as a client, simply call WebSocketPeer.coonect_to_url, then frequently poll the peer until STATE_OPEN is reached and then you can write or read from it, or STATE_CLOSED and then you can check the disconnect code and reason). To implement a server instead, a TCPServer must be created, and the accepted connections needs to be provided to WebSocketPeer.accept_stream (which will perform the HTTP handshake). A full example of a WebSocketServer using TLS will be provided in the demo repository.

[NET] Refactor TLS configuration. Use a TLSOptions configuration object which is created via static functions. - "TLSOptions.client": uses the standard CA and common name verification. - "TLSOptions.client_unsafe": uses optional CA verification (i.e. if specified) - "TLSOptions.server": is the standard server configuration (chain + key) This will allow us to expand the TLS configuration options to include e.g. mutual authentication without bloating the classes that uses StreamPeerTLS and PacketPeerDTLS as underlying peers.
