    tools: Add bench tools for accept(2) and connect(2)
    
    The main reasons behind making these tools instead of using netperf TCP_CC
    test are:
    - Netperf TCP_CC creates new server for each testing client
    - Netperf TCP_CC creates new listen socket on different TCP port for each
      testing client
    - Netperf TCP_CC created listen socket is in blocking mode
    - Netperf TCP_CC closes accepted sockets immediately
    
    All of the above listed items make netperf TCP_CC do not reflect real life
    TCP server usage.
    
    Tools in accept_connect:
    - "connect_client"
      Fork certain amount of processes to perform blocking connect(2)/close(2)
      for the certain amount of time.
    - "accpet_server"
      Fork certain amount of processes to perform blocking accept(2) on the same
      addr/port bound socket.  close(2) on the accepted socket is called
      immediately.  If -r is specified, each processes will create their own
      listen socket on the same port/addr w/ SO_REUSEPORT sockopt.
    - "kq_accept_server"
      Fork certain amount of processes to perform non-blocking accept(2) on the
      same addr/port bound socket w/ help of kqueue(2).  close(2) on the accepted
      socket is called after the other side closed the connection.  If -r is
      specified, each processes will create their own listen socket on the same
      port/addr w/ SO_REUSEPORT sockopt.
    
    kq_accept_server closely mimics the real life TCP server.
