Support byte oriented mode in dgram sockets.

* socket.c (struct dgram_stream): New member, is_byte_oriented.
(dgram_get_char): In byte oriented mode, just get one byte
and convert to a character just like stdio_get_char: zero
goes to U+DC00, and 0x01-0xFF go to U+0001 to U+FFFF.
(dgram_get_prop, dgram_set_prop): Handle :byte-oriented
property for getting and setting the is_byte_oriented flag.
