A GProxy handles connecting to a remote host via a given type of proxy server. It is implemented by the 'gio-proxy' extension point. The extensions are named after their proxy protocol name. As an example, a SOCKS5 proxy implementation can be retrieved with the name 'socks5' using the function g_io_extension_point_get_extension_by_name().
Asynchronous version of g_proxy_connect().

Some proxy protocols expect to be passed a hostname, which they will resolve to an IP address themselves. Others, like SOCKS4, do not allow this. This function will return FALSE if proxy is implementing such a protocol. When FALSE is returned, the caller should resolve the destination hostname first, and then pass a gio.ProxyAddress containing the stringified IP address to g_proxy_connect() or g_proxy_connect_async().
