* frame.c (has_stack_frames): Make public.
(get_prev_frame): Don't allow a NULL this_frame anymore. * frame.h (has_stack_frames): Declare. * varobj.c (find_frame_addr_in_frame_chain): Don't ever pass NULL to get_prev_frame, instead start at get_current_frame. (varobj_create): Check has_stack_frames before getting any frame; eliminate one usage of deprecated_safe_get_selected_frame.
