Jumbo patch, resync of W3C/Gnome CVS trees:
- uri.c tree.c SAX.c parser.c entities.c debugXML.c: finished
  the cleanup of the computation of URI references when seeking
  external entities. The URI reference string and the resulting
  URI are both stored now.
- parser.c HTMLparser.c valid.c nanoftp.c nanohttp.c xpath.c:
  large s(n)printf checks and cleanup from Denis Barbier
  <barbier@imacs.polytechnique.fr>
- xmlversion.h.in tree.h: couple of SGML declarations for a
  possible docbook module.
- result/VC/ : a couple of test output changed due to the change
  of the entities URI
