      Suppress cppcheck 1.89 false positive · db7fd163
      Michał Kępień authored 
      cppcheck 1.89 emits a false positive for lib/dns/spnego_asn1.c:

    lib/dns/spnego_asn1.c:698:9: error: Uninitialized variable: data [uninitvar]
     memset(data, 0, sizeof(*data));
            ^
    lib/dns/spnego.c:1707:47: note: Calling function 'decode_NegTokenResp', 3rd argument '&resp' value is <Uninit>
     ret = decode_NegTokenResp(buf + taglen, len, &resp, NULL);
                                                  ^
    lib/dns/spnego_asn1.c:698:9: note: Uninitialized variable: data
     memset(data, 0, sizeof(*data));
            ^

This message started appearing with cppcheck 1.89 [1], but it will be
gone in the next release [2], so just suppress it for the time being.

      Fix cppcheck 1.89 warnings · abfde3d5

      cppcheck 1.89 enabled certain value flow analysis mechanisms [1] which
trigger null pointer dereference false positives in lib/dns/rpz.c:

It seems that cppcheck no longer treats at least some REQUIRE()
assertion failures as fatal, so add extra assertion macro definitions to
lib/isc/include/isc/util.h that are only used when the CPPCHECK
preprocessor macro is defined; these definitions make cppcheck 1.89
behave as expected.

There is an important requirement for these custom definitions to work:
cppcheck must properly treat abort() as a function which does not
return.  In order for that to happen, the __GNUC__ macro must be set to
a high enough number (because system include directories are used and
system headers compile attributes away if __GNUC__ is not high enough).
__GNUC__ is thus set to the major version number of the GCC compiler
used, which is what that latter does itself during compilation.
