* Added flags field in net_protocol_module_info; there is currently a single

defined flag: NET_PROTOCOL_ATOMIC_MESSAGES.
* socket_send() now honours NET_PROTOCOL_ATOMIC_MESSAGES and returns either
  EMSGSIZE if the data to be send is larger than net_socket::send::buffer_size,
  or divides the data in appropriately sized chunks.
* This fixes sending >=64K over a TCP socket at once (TCP would just have
  returned an error in that case).
* TCP now overrides the default send buffer size (to 32768 for now).
