Subject: Introducing optional arguments.

* debug.c (help, show_bindings): put_string arguments reversed.

* eval.c (bind_args): Support colon notation in interpreted
function lambda lists for optional arguments. Improved error checking.
(apply): Allow optional arguments to be left out.
(dwim_loc): Reversed arguments to replace_str, replace_vec,
replace_list.
(eval_init): Numerous intrinsics now have arguments that are optional.
New function rand introduced which reverses arguments relative to
random. New intrinsic function hash introduced for alternative
construction of hashes.

* gc.c (sweep): Reversed arguments to put_char.

* hash.c (weak_keys_k, weak_vals_k, equal_based_k): New keyword
symbol variables.
(hashv): New function.
(hash_init): Intern new symbols.

* hash.h (weak_keys_k, weak_vals_k, equal_based_k, hashv): Declared.

* lib.c (colon_k): New keyword symbol variable.
(replace_list, replace_str, replace_vec): Arguments rearranged.
(tree_find): testfun becomes optional argument.
(int_str): base becomes optional argument.
(func_f0, func_f1, func_f2, func_f3, func_f4, func_n0,
func_n1, func_n2, func_n3, func_n4,  func_f0v, func_f1v,
func_f2v, func_f3v, func_f4v, func_n0v, func_n1v,
func_n2v, func_n3v, func_n4v, func_interp): Initialize optargs to zero.
(func_n0o, func_n1o, func_n2o, func_n3o, func_n4o): New functions.
(cobj_print_op): Reversed arguments to put_string.
(find): testfun and keyfun become optional arguments.
(replace): Parameters rearranged and arguments rearranged in calls to
replace_list, replace_str and replace_vec.
(obj_init): colon_k initialized.
(obj_print, obj_pprint): Arguments reversed, and stream defaults
to std_output. Arguments reversed in calls to put_char and put_string.
(dump): Arguments reversed in call to put_char.

* lib.h (struct func): sizes of minparam, fixparam bitfields
adjusted. New bitfield optargs. New unnamed bitfield added so
the previous ones add up to 16 bits.
(colon_k): Declared.
(func_n0o, func_n1o, func_n2o, func_n3o, func_n4o): Declared.
(replace_list, replace_str, replace_vec, replace): Declarations updated.

* match.c (debuglf, dump_shell_string, dump_byte_string, dump_var,
do_output_line, extract): Reversed arguments to put_char and
