    tcp: watch out for pcb->nrtx overflows and tcp_backoff indexing overflow

commit 5827c168c28b43d98ffbf91f45c38a054e848eda
Author: David van Moolenbroek <address@hidden>

    tcp: do not keep sending SYNs when getting ACKs
    
    If a locally generated TCP SYN packet is replied to with an ACK
    packet, lwIP immediately sends a RST packet followed by resending the
    SYN packet.  This is expected, but on loopback interfaces the resent
    SYN packet may immediately get another ACK reply, typically when the
    other endpoint is in TIME_WAIT state (which ignores the RSTs).  The
    result is an endless loop of SYN, ACK, RST packets.
    
    This patch applies the normal SYN retransmission limit in this
    scenario, such that the endless loop is limited to a brief storm.
