Size mode meaningful in datagram sockets.

* socket.c (struct dgram_stream): new rx_max member.
(make_dgram_sock_stream): New arguments: a struct stdio_mode,
and pointer to prototype dgram socket. If a size is specified
in the mode, then use that as rx_max. Otherwise if a prototype
socket is specified, use its rx_max as the new socket's rx_max.
Otherwise default on 65536.
(dgram_get_byte_callback): Use d->rx_max as the capture size,
rather than a hard-coded 65536.
(sock_accept): Use d->rx_max as capture size for datagram.
Parse the mode. Pass the parsed mode to make_dgram_sock_stream,
as well as the accepting socket, so it can set up the rx_max
for the new socket.
(open_sockfd): Parse the mode and pass to make_dgram_sock_stream.

* stream.c (parse_mode): Static function becomes extern.

* stream.h (parse_mode): Declared.

* txr.1: Documented.
