/*
 * Private usage only.

 * @uri: the URI we want to know the User-Agent for
 *
 * Some web sites have been using User-Agent parsing heavily to decide
 * the kind of content that is sent to the browser. When
 * WebKitWebSettings:enable-site-specific-quirks is enabled WebKitGTK+
 * will use its knowledge of sites doing bad things and lie to them by
 * sending either the default User-Agent, i.e. not using the one
 * specified by the browser in WebKitWebSettings:user-agent, or the
 * Safari one (including lying about the underlying operating system).
 *
 * This function allows the browser to figure out what User-Agent is
 * going to be sent to a particular URI.
 *
 * Please note that if WebKitWebSettings:use-site-specific-quirks is
 * turned off calling this function is the same as calling
 * webkit_web_settings_get_user_agent(), except you have to free the
