Multi-line, indented printing of structure.

* eval.c (op_error): New static function.
(macro_form_p, fboundp): Static to external.
(special_operator_p): New function.
(eval_init): Register macrolet and symacrolet to op_error.
These are recognized and processed by expand, but we want
them in the op table so they are reported by special_operator_p.

* eval.h (fboundp, macro_form_p, special_operator_p): Declared.

* hash.c (print_key_val): Break long lines on spaces
between pairs with stream_width_check.
(hash_print_op): Implement split and indented printing.

* lib.c (obj_print_impl): New static function, resulting
from a merge of obj_print and obj_pprint. Fixes some
wrong-way recursion bugs: obj_pprint recursed into obj_print
in some places. Adds support for multi-line printing of
vectors and lists, with indentation using the new
interfaces in streams.

* stream.c (strm_base_init): Update initializer.
(put_indent, indent_mode_put_string): New static functions.
(put_string): Use indent_mode_put_string in either of the
two indent modes.
(put_char): Implement indent mode.
(get_indent_mode, test_set_indent_mode,
set_indent_mode, get_indent, set_indent,
inc_indent, width_check): New functions.

* stream.h (enum indent_mode): New.
(struct strm_base): indent_on member becomes indent_mode.
New members data_width and code_width.
(get_indent_mode, test_set_indent_mode,
set_indent_mode, get_indent, set_indent,
inc_indent, width_check): Declared.

* tests/009/json.expected: Updated.

* tests/010/seq.expected: Likewise.

* tests/011/macros-2.expected: Likewise.
