cl-pushnew and other functions

[John Wiegley]

Why are we moving toward a "cl-" prefix for Common Lisp macros?  Why can we
not have function like pushnew in the global namespace?  I think Emacs Lisp
authors can benefit from a lot of these macro and functions, but I think it's
very unfortunate if code is going to start getting littered with "cl-"
prefixes for such common uses.  Are we going to have cl-dolist and cl-incf,
etc?

I think the basic function in CL should just be considered part of the Emacs
Lisp language, the same way that we have dolist in subr.el now.
