get the protocol more right

Include some generic function arguments for specialization in protocol
functions involving generalizers.  (Otherwise there are some cases where
it's not possible to define methods not in violation of the rules about
specializers applicable to instances of not-standard classes.)

Adjust the CONS-SPECIALIZER example to suit, and include an extra test
case which shows of method-combination as well as the new ability to
have multiple applicable methods with class specializers.

handle arbitrary method combination

I think it's practically impossible to do on our own, certainly
efficiently: handling the pseudo-lisp that is an effective method is
likely to go wrong.  Piggy-back on SBCL, with

initial commit

Somewhat modified version of specializable.lisp from
http://www.lichteblau.com/git/?p=specializable.git
[ commit eb30d235951c3c1d128811278760f1db36cd336c ]

Lightly modified on a first read-through, mostly cosmetic though with
the innovation of the GENERALIZER concept, as in
COMPUTE-APPLICABLE-METHODS-USING-GENERALIZER and
SPECIALIZER-ACCEPTS-GENERALIZER-P.  Lots of FIXME notes for the things
that weren't trivial.
