compiler: improvements in reporting form in diagnostics.

* eval.c (ctx_name): Do not report just the car
of the form. If the form starts with three symbols,
list those; if two, list those.

* stdlib/compiler.tl (expand-defun): Set the
defun form as the macro ancestor of the lambda,
rather than propagating source location info.
Then diagnostics that previously refer to a
lambda will correctly refer to the defun and
thank to the above change in eval.c, include
its name.

* stdlib/pmac.t (define-param-expander):
A similar change here. We make the define-param-expander
form the macro ancestor of the lambda, so that
diagnostics agains tthe lambda will show that
form.
