commit 849dfb17c70ff6872355c0ffb7fc21177c536033
Author: Dirk Ziegelmeier <[email protected]>
Date:   Sun Nov 5 10:27:46 2017 +0100

    The macros in ip6_addr.c are duplicated from ip4_addr.c, so move them to lwIPs portability layer
    ...didn't see that in the first place...

commit 93f4245e895bd409e9cccb8f0aaac59a67d83c58
Author: Dirk Ziegelmeier <[email protected]>

    ip6_addr.c: Convert several macros to private #defines
    The macros are functions from ctype.h, but ctype.h declares them as functions, not as #defines
    It makes no sense to abstract them in lwIPs portability layer, the functions are of low complexity and they are only used in this file.

Date:   Sun Nov 5 10:06:25 2017 +0100

    Make xchar() a private #define of ip6_addr.c, it is not standardized in any C header

    Apply patch #9478: MQTT.c printf warning in debug messages
    in a modified version that uses lwIP's format string #defines
