* Makefile.am configure.in include/libxml/xmlwin32version.h:
  preparing for a 2.4.3 release even if it may not be ready yet
* catalog.c parser.c xmlIO.c include/libxml/catalog.h: redirected
  all file parsing lookup to go through the entity resolver, add
  to add an API to bypass it (needed to load catalogs themselves),
  some cleanup on the catalog code too.
* nanoftp.c: small cleanup
* doc/catalog.html: small update
