  made configuring with regexps/automata/unicode the default
  but without schemas ATM
* testRegexp.c valid.c xmlregexp.c include/libxml/xmlregexp.h:
  fixed the regexp based DTD validation performance and memory
  problem by switching to a compact form for determinist regexps

  as fast as the old DTD validation specific engine :-) despite
  the regexp built and compaction process.
