macroexpand-all

One of the cl functions Martin wanted for cc-mode was `macroexpand-all'.

I'd like to add the following file to emacs, `lisp/emacs-lisp/macroexp.el',
which implements `macroexpand-all'.  I wrote it for my lexical-binding
branch, in which _all_ compiler macroexpansion is done using macroexpand-all
on top-level file forms, so it's received a fair bit of testing (at least,
all of emacs lisp code has passed through it :-).

One unusual point is that this implementation also tries to avoid consing in
the case where a form contains no macros (as is true of many).

Any objections/comments?

Objections?  Hell no!
Please do it.  Then we can pass the content of `interactive' specs
through it easily, so we can then use CL macros in interactive specs
without having to load CL at runtime.

I don't mind.  It should go into emacs-lisp directory.
