Added bit flags to type parameter of nxt_port_socket_write().

Browse Source 
NXT_PORT_MSG_LAST     - mark message as last;
NXT_PORT_MSG_CLOSE_FD - close fd right after send;

Type constants altered to include last flag for single buffer messages.

Last sign is critical for coming port RPC layer. Handlers unregistered on last
message. Create sync buffer is not convenient, extra parameter is better.
