    tcp: fix cwnd rollover introduced by ABC
    
    Changes for TCP Appropriate Byte Counting introduce a potential cwnd
    rollover by not taking into account integer promotion on tcpwnd_size_t
    during inequality comparisions
    
    This fixes the issue by introducing a macro TCP_WND_INC which detects
    the rollover correctly and now holds the tcpwnd_size_t at the maximum
    value rather than not incrementing the window.  This provides a slight
    performance improvement by allowing full use of the tcpwnd_size_t number
    space for the congestion window
