Azure RTOS 6.1.10

Azure RTOS NetX Duo 6.1.10 release contains the following features and changes:

    Files are modified to fix unsigned integers comparison that signed overflow in C is undefined:
        common/src/nx_icmpv6_send_error_message.c
        common/src/nx_tcp_socket_packet_process.c
        common/src/nx_tcp_socket_state_ack_check.c

        common/src/nxd_udp_socket_send.c           Corrected the logic for queued packet on TCP/IP offload interface since
                                                     the upper layer always treats the prepend pointer at UDP header for retransmission.

                                                   Corrected the return value of nx_azure_iot_hub_client_reported_properties_send().

        addons/snmp/nxd_snmp.c                     Initialized the sequence byte value.

        addons/web/nx_web_http_server.c            Fixed the HTTP Server state issue with basic authorization.
