Use of new args for function calls in interpreter.

* args.c (args_copy_to_list): New function.

* args.h (ARGS_MIN): New preprocessor symbol.
(args_add_list): New inline function.
(args_copy_to_list): Declared.

* debug.c (debug): Args in debug frame are now struct args *.
Pull them out nondestructively for printing using
args_copy_to_list.

* eval.c (do_eval_args): Fill struct args argument list
rather than returning evaluated list.
Dot position evaluation is handled by installing
the dot position value as args->list.
(do_eval): Allocate args of at least ARGS_MAX for the
call to do_eval_args. Then use generic_funcall to
invoke the function rather than apply.
(eval_args_lisp1): Modified similarly to do_eval_args.
(eval_lisp1): New static function.
(expand_macro): Construct struct args argument list for
the sake of debug_frame.
(op_dwim): Allocate args which are filled by eval_args_lisp1,
and applied to the function/object with generic_funcall.
The object expression is separately evaluated with
eval_lisp1.

* match.c (h_fun, v_fun): Construct struct args arglist for
the sake of debug_frame call.

* unwind.c (uw_push_debug): args argument becomes
struct args *.

* unwind.h (struct uw_debug): args member becomes
struct args *.
(uw_push_debug): Declaration updated.

* txr.1: Update documentation about dot position argument in
function calls. (list . a) now works, which previously didn't.
