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
#GProxyAddress containing the stringified IP address to
g_proxy_connect() or g_proxy_connect_async().
Return: %TRUE if hostname resolution is supported.
