f2e9afdf42 Port RPC interface introduced. 
Usage:
1. Register handlers in incoming port with nxt_port_rpc_register_handler().
2. Use return value as a stream identifier for next nxt_port_socket_write().

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.

nxt_req_conn_link_t still used for lookup connection by request id.
New nxt_req_app_link_t (ra) allocated from conn->mem_pool using mp_retain().
ra stored in app->requests if there is no free worker to process request.

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.
