New feature: structure delegate streams.
A new kind of stream object which redirects its operations to
the methods of a structure.
* Makefile (OBJS): New object file, strudel.o.
* lib.c (init): Call new strudel_init function.
* lisplib.c (stream_wrap_set_entries,
stream_wrap_instantiate): New static functions.
(lisplib_init): Arrange for autloading of new stream-wrap.tl.
* share/txr/stdlib/stream-wrap.tl: New file.
* stream.c (put_string_s, put_char_s, put_byte_s, get_line_s,
get_char_s, get_byte_s, unget_char_s, unget_byte_s, put_buf_s,
fill_buf_s, flush_s, seek_s, truncate_s, get_prop_s,
set_prop_s, get_error_s, get_error_str_s, clear_error_s,
get_fd_s): New symbol variables.
(stream_init): New symbol variables initialized. Numerous
functions registered via these variables now rather than
intern(...) expressions.
* stream.h (put_string_s, put_char_s, put_byte_s, get_line_s,
get_char_s, get_byte_s, unget_char_s, unget_byte_s, put_buf_s,
fill_buf_s, flush_s, seek_s, truncate_s, get_prop_s,
set_prop_s, get_error_s, get_error_str_s, clear_error_s,
get_fd_s): Declared.
* strudel.c, strudel.h: New files.
