* arith.c (lognot): Conform to new scheme for defaulting optional args.

* eval.c (apply): Unconditionally use colon_k for missing optional
args, for intrinsic functions.
(eval_intrinsic, rangev, rangev_star, errno_wrap): Conform to new
scheme for defaulting optional args.
(reg_fun_mark): Function removed.
(eval_init): Switch reduce_left and reduce_right back to reg_fun
registration.

arguments.

Remove references to removed mark_missing_args member of struct func.
(func_set_mark_missing): Function removed.
(generic_funcall): Unconditionally use colon_k for missing optional
args, for intrinsic functions.

* lib.h (struct func): mark_missing_args member removed.
(func_set_mark_missing): Declaration removed.
(default_arg, default_bool_arg): New inline functions.

* rand.c (random): Left argument is not optional.
(rnd): Conform to new scheme for defaulting optional arguments.

* regex.c (search_regex, match_regex): Conform to new scheme for
defaulting optional arguments.

* stream.c (unget_char, unget_byte, put_string, put_char, put_byte,
put_line): Conform to new scheme for defaulting optional arguments.

* syslog.c (openlog_wrap): Conform to new scheme for defaulting
optional arguments.

* txr.1: Remove the specification that nil is a sentinel value in
default arguments, where necessary. Use consistent syntax for
specifying variable parts in argument lists. A few errors and omissions
addressed.
