There is already a frame parameter called 'display, so making
x-display-name a frame-local variable is redundant.  Anyway, it is
useful to have a way of knowing which display Emacs started on.

I suggest keeping the current behavior, and updating the docstring of
x-display-name to say that it reflects where Emacs started, plus a
reference to the 'display frame parameter.
