This patch introduces three new IPC calls for WebContent: - `Client::did_output_js_console_message(index)`: Notifies the client that a new console message was logged. - `Server::js_console_request_messages(start_index)`: Ask the server for console messages starting at the given index. - `Client::did_get_js_console_messages(start_index, types, messages)`: Send the client the messages they requested. This mechanism will replace the current `Client::did_js_console_output()` call in the next few commits. This will allow us to display messages in the console that happened before the console was opened.
