 * #GSocketClient is a lightweight high-level utility class for connecting to
 * a network host using a connection oriented socket type.

 * call a sync or async connect operation, which returns a #GSocketConnection
 * subclass on success.
 * 
 * The type of the #GSocketConnection object returned depends on the type of
 * the underlying socket that is in use. For instance, for a TCP/IP connection
 * it will be a #GTcpConnection.
 * 
 * As #GSocketClient is a lightweight object, you don't need to cache it. You
 * can just create a new one any time you need one.

	 *
	 * - %G_SOCKET_CLIENT_RESOLVED:  @client has successfully resolved
	 * @connectable in DNS. @connection will be %NULL.
	 *
	 * - %G_SOCKET_CLIENT_CONNECTING: @client is about to make a connection
	 * to a remote host; either a proxy server or the destination server
	 * itself. @connection is the #GSocketConnection, which is not yet
	 * connected.  Since GLib 2.40, you can access the remote
	 * address via g_socket_connection_get_remote_address().
	 *
	 * - %G_SOCKET_CLIENT_CONNECTED: @client has successfully connected
	 * to a remote host. @connection is the connected #GSocketConnection.
	 *
	 * - %G_SOCKET_CLIENT_PROXY_NEGOTIATING: @client is about to negotiate
	 * with a proxy to get it to connect to @connectable. @connection is
	 * the #GSocketConnection to the proxy server.
	 *
	 * - %G_SOCKET_CLIENT_PROXY_NEGOTIATED: @client has negotiated a
	 * connection to @connectable through a proxy server. @connection is
	 * the stream returned from g_proxy_connect(), which may or may not
	 * be a #GSocketConnection.
	 *
	 * - %G_SOCKET_CLIENT_TLS_HANDSHAKING: @client is about to begin a TLS
	 * handshake. @connection is a #GTlsClientConnection.
	 *
	 * - %G_SOCKET_CLIENT_TLS_HANDSHAKED: @client has successfully completed
	 * the TLS handshake. @connection is a #GTlsClientConnection.
	 *
	 * - %G_SOCKET_CLIENT_COMPLETE: @client has either successfully connected
	 * to @connectable (in which case @connection is the #GSocketConnection
	 * that it will be returning to the caller) or has failed (in which
	 * case @connection is %NULL and the client is about to return an error).
	 *
	 * Each event except %G_SOCKET_CLIENT_COMPLETE may be emitted
	 * multiple times (or not at all) for a given connectable (in
	 * particular, if @client ends up attempting to connect to more than
	 * one address). However, if @client emits the #GSocketClient::event
	 * signal at all for a given connectable, that it will always emit
	 * it with %G_SOCKET_CLIENT_COMPLETE when it is done.
	 *
	 * Note that there may be additional #GSocketClientEvent values in
	 * the future; unrecognized @event values should be ignored.

	 *     event = the event that is occurring
