I discovered that for myself last night, but was too tired to write
another email.  However, it still doesn't get the actual *name* of the
symbol.

Then it occurred to me that although it's rather heavyweight, once
I know I have a symbol I can use qprint() to return its name.  Likewise,
qmksym() is only useful for creating a qexpr for a well-known symbol;
it returns -1 if the symbol is not known.  So I'll use qparse() to
create a qexpr for a potentially-unknown symbol coming from Scheme.

The only remaining issues are on the Scheme side: how to create a
Scheme bignum from an mpz_t, and what to do about Q foreign objects
on the Scheme side (probably just wrap them in a specialized
Scheme type).
