* configure.in doc/* : 2.6.0beta1 changes
* SAX2.c hash.c parser.c parserInternals.c: Fixing attribute
  normalization, might not be totally fixed but this should
  make sure SAX event provide the right strings for attributes
  except entities for which libxml2 is different by default
  This should fix #109564
* result/attrib.xml.sax result/ent3.sax result/p3p.sax: minor changes
  in attribute callback values
* result/c14n/with-comments/example-4
  result/c14n/without-comments/example-4: this also fixes a subtle
  bug in the canonicalization tests.
