display-buffer-function obsolete since 24.3

[Leo Liu]

Hi there,

Before we have a single entry to control display-buffer now it seems it
has become complicated:

  display-buffer-overriding-action
  display-buffer-alist
  display-buffer-base-action
  display-buffer-fallback-action

Does this complexity offer a superset of display-buffer-function? For
example, what is a most reliable way to make display-buffer a noop?

Thanks,
Leo
