This also required adding the same feature that supported recentering/scrolling
in y-or-n-p to the minibuffer as well.  A large part of old implementation
of y-or-n-p handled recentering/scrolling.  Now the minibuffer supports
the same commands by using the new macro 'with-minibuffer-selected-window'.

window.c was changed to use the 'lambda' value for MINIBUF arg of 'next-window',
so minibuffer-scroll-other-window/minibuffer-scroll-other-window-down
doesn't try to scroll the minibuffer window.

A new history variable 'y-or-n-p-history-variable' is nil by default,
so no history is used in 'y-or-n-p' minibuffer.

This patch was tested with various commands that use 'y-or-n-p'
and seems to work fine:
