           Security fixes:
          #531 #534  CVE-2021-45960 -- Fix issues with left shifts by >=29 places
                       resulting in
                         a) realloc acting as free
                         b) realloc allocating too few bytes
                         c) undefined behavior
                       depending on architecture and precise value
                       for XML documents with >=2^27+1 prefixed attributes
                       on a single XML tag a la

                       where XML_ParserCreateNS is used to create the parser
                       (which needs argument "-n" when running xmlwf).
                       Impact is denial of service, or more.

                       on variable m_groupSize in function doProlog leading
                       to realloc acting as free.
                       Impact is denial of service or more.
