Overhaul printing of lazy strings.

The #<lazy-string ...> print syntax is gone.  Lazy strings are
now printed by traversing their structure, without forcing
them to the flat representation.

* lib.c (lazy_str_put): New function.
(out_str_char, out_str_pretty, out_lazy_str): New static functions.
(obj_print_impl): Use out_str_pretty for standard-printing
regular strings. Use lazy_put_str for pretty-printing lazy
strings, and out_lazy_str for standard-printing them.

* lib.h (lazy_str_put): Declared.

* stream.c (put_string): Check for a lazy string and route
to lazy_str_put, so the string doesn't get forced
(though of course the underlying list does, if it is lazy).
