ffi: diagnose missing with-dyn-lib.
If the programmer writes a deffi, deffi-sym or deffi-var that
makes simple references, and that macro is not wrapped in
with-dyn-lib, an unhelpful error message results about
sys:ffi-lib being unbound. We can detect this situation and
provide a warning.
* share/txr/stdlib/ffi.tl (sys:with-dyn-lib-check,
sys:expand-sym-ref): New functions.
(deffi, deffi-sym, deffi-var): Capture environment parameter.
Common code replaced by call to sys:expand-sym-ref, where the
missing sys:ffi-lib situation is diagnosed. This is only done
in cases when the simple reference syntax occurs.
