CLN instead of mpwrap

[George <jirka@5z.com>]

I'm investigating how to replace mpwrap and a lot of the genius routines with
CLN.  So perhaps you may see some genius breakage in the coming days because
of this.  This may actually speed up the process of the new interface as it
will take care of modularizing a large part of the engine.  It also seems
like cln will be quite a bit faster then mpwrap which eats cache for
breakfast.

The only thing is that I can't find rpms for this beast.  The homepage is at
http://clisp.cons.org/~haible/packages-cln.html

Lemme know what you think about this.  It should definately improve
precision, speed and features of dr genius.  And I think it will be simpler
then trying to make mpwrap work nicely.  Also it offloads the burden of
maintaining some of the math stuff from genius which means more time for
other stuff.

(And yes aaron it does have fast low precision floats for you:)
