  - Large resync between W3C and Gnome tree
  - configure.in: 2.1.0 prerelease
  - example/Makefile.am example/gjobread.c tree.h: work on
    libxml1 libxml2 convergence.
  - nanoftp, nanohttp.c: fixed stalled connections probs
  - HTMLtree.c SAX.c : support for attribute without values in
    HTML for andersca
  - valid.c: Fixed most validation + namespace problems
  - HTMLparser.c: start document callback for andersca
  - debugXML.c xpath.c: lots of XPath fixups from Picdar Technology
  - parser.h, SAX.c: serious speed improvement for large
    CDATA blocks
  - encoding.[ch] xmlIO.[ch]: Improved seriously saving to
    different encoding
  - config.h.in parser.c xmllint.c: added xmlCheckVersion()
    and the LIBXML_TEST_VERSION macro
