[forms] deprecate form_render(**kwargs) in favor of render(formvalues=None, rendervalues=None, renderer=None) to fix a pitfall in form_render prototype: there is no way to distinguish between arguments that should be given to build_context from arguments that should be given to the renderer. This was problematic for instance with inlined form where a 'title' argument is given for the renderer, but is also used as default value for field whose name is 'title'...

function load_now(eltsel, holesel, reloadable) {
    var lazydiv = jQuery(eltsel);
    var hole = lazydiv.children(holesel);
    if ((hole.length == 0) && !reloadable) {
	/* the hole is already filled */
	return;
    }
    lazydiv.loadxhtml(lazydiv.attr('cubicweb:loadurl'));
}

function trigger_load(divid) {
    jQuery('#lazy-' + divid).trigger('load_' + divid);
