   Introduce NAPI ID based worker thread selection
   By default memcached assigns connections to worker threads in
   a round-robin manner. This patch introduces an option to select
   a worker thread based on the incoming connection's NAPI ID if
   SO_INCOMING_NAPI_ID socket option is supported by the OS.
   
   This allows a memcached worker thread to be associated with a
   NIC HW receive queue and service all the connection requests
   received on a specific RX queue. This mapping between a memcached
   thread and a HW NIC queue streamlines the flow of data from the
   NIC to the application. In addition, an optimal path with reduced
   context switches is possible, if epoll based busy polling
   (sysctl -w net.core.busy_poll = <non-zero value>) is also enabled.
   
   This feature is enabled via a new command line parameter -N <num>
   or "--napi_ids=<num>", where <num> is the number of available/assigned
   NIC hardware RX queues through which the connections can be received.
   The number of napi_ids specified cannot be greater than the number
   of worker threads specified using -t/--threads option.
   If the option is not specified, or the conditions not met, the code
   defaults to round robin thread selection.
