Implementing put_byte for string output stream.

This does the Right Thing with a mixture of bytes and characters.
Incomplete byte sequences.

* stream.c (struct strm_ops): Changing byte argument of put_byte
to int, since the put_byte API function can just pass down that
value after validating it.
(stdio_handle): Use available typedef.
(stdio_put_byte): Follow interface change in strm_ops.
Do not validate the range of a byte; the put_byte higher
level function does that now.
(struct string_output): New members: ud, byte_buf, head, tail.
(string_out_byte_callback, string_out_byte_flush): New static
functions.
(string_out_put_string): Flush any UTF-8 bytes in the byte buffer
before putting the string.
(string_out_put_byte): New static function, implementation for
put_byte on string output streams.
(string_out_ops): string_out_put_byte wired in.
(make_string_output_stream): Initialize new members of
of struct string_output.
(get_string_from_stream): Flush any UTF-8 bytes in the byte buffer
before retrieving the string.
(put_byte): Validate that the byte is in range. Pass byte
as C int down to the put_byte virtual.
