cursor-in-non-selected-windows in edebug

[Juri Linkov]

I use cursor-in-non-selected-windows=nil, because it is difficult to
quickly locate a window with the active cursor, and I never needed its
default behavior, with only one exception.  In edebug, displaying a
cursor in non-selected windows is necessary to follow point movements
in another window.

After looking for a way to enable it in edebug, I noticed the inviting
comment that says "any others??" just after binding
`cursor-in-echo-area' to nil in `edebug-display'.  The patch below
accepts this invitation and binds `cursor-in-non-selected-windows'
to t in the same places.  But unlike `cursor-in-echo-area' it needs
special treatment because `cursor-in-non-selected-windows' is
automatically buffer-local.  I believe no one might want to have
`cursor-in-non-selected-windows' disabled while edebug is active
even when its value is set to nil.
