json: fix circular printing.

The recursive JSON printer must check for the circularity
circularity-related conditions and emit #n= and #n# notations.

* lib.c (circle_print_eligible): Function moved before
out_json_rec to avoid a forward declaration.
(check_emit_circle): New static function. This is a block of
code for doing the circular  logic, taken out of
obj_print_impl, because we would like to use it in
out_json_rec.
(out_json_rec): Call check_emit_circle to emit any #n= or #n#
notation. The function returns 1 if it has emitted #n#,
in which a se we are done.
(obj_print_impl): Replace moved block of code with call to
check_emit_circle.
