3812ffd336 Added bit flags to type parameter of nxt_port_socket_write(). 
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.

74cda90e31 Process stop notification from master to all other processes. 
New port message type introduced NXT_PORT_MSG_REMOVE_PID. Default handler
removes process description from nxt_runtime_t with all ports, incoming and
outgoing mmaps etc.

f319220a6c Redirecting buffer completion handler to specific engine. 
There is a case in router where we use port in router connection thread.
Buffers are allocated within connection memory pool which can be used only in
this router thread. sendmsg() can be postponed into main router thread and
completion handler will compare current engine and post itself to correct
engine.

f7b4bdfd89 Using shared memory to send data via nxt_port. 
Usage:
    b = nxt_port_mmap_get_buf(task, port, size);
    b->mem.free = nxt_cpymem(b->mem.free, data, size);
    nxt_port_socket_write(task, port, NXT_PORT_MSG_DATA, -1, 0, b);
