gtk:info-bar-add-buttons (infobar &rest args)

infobar -- a gtk:info-bar widget
args -- first a string for a button text and second an integer for a response ID, then more pairs for each button

Adds more buttons, same as calling the gtk:info-bar-add-button function repeatedly. Each button must have both text and a response ID. The gtk:info-bar implementation is deprecated since 4.10. Do not use it in newly written code.
