symbol-function: support lambda expressions.

* eval.c (lookup_fun): Check for a lambda expression and
return a faked binding containing the interpreted function.
(do_eval, op_fun): Remove checks for lambda that are now
being done in lookup_fun. In many other places where
lookup_fun is used, we still need lambda checks, like
in the expander.

* share/txr/stdlib/place.tl (sys:get-fun-getter-setter): Take
form argument. Diagnose assignments to lambda, and to unknown
function place syntax.
(defplace symbol-function): Pass sys:*pl-form* to
sys:get-fun-getter-setter as form argument.

* txr.1: fboundp and symbol-function doc updated.
