* encoding.c, parser.c, xmlstring.c, Makefile.am,
  include/libxml/Makefile.am, include/libxml/catalog.c,
  include/libxml/chvalid.h, include/libxml/encoding.h,

  moved string and UTF8 routines out of parser.c and encoding.c
  into a new module xmlstring.c with include file
  include/libxml/xmlstring.h mostly using patches from Reid
  Spencer.  Since xmlChar now defined in xmlstring.h, several
  include files needed to have a #include added for safety.
* doc/apibuild.py: added some additional sorting for various
  references displayed in the APIxxx.html files.  Rebuilt the
  docs, and also added new file for xmlstring module.
* configure.in: small addition to help my testing; no effect on
  normal usage.
* doc/search.php: added $_GET[query] so that persistent globals
  can be disabled (for recent versions of PHP)
