* xmlreader.c include/libxml/xmlreader.h: applied patch from
  Aron Stansvik to add xmlTextReaderByteConsumed()
* testReader.c: added a test option
* xmlschemastypes.c: fix a lack of pointer checking in APIs

  xmlreader.c example/gjobread.c include/libxml/xmlversion.h.in:
  added 2 new configure option: --with-reader --with-sax1
  to allow removing the reader or non-xmlReadxxx() interfaces.

* testReader.c xmlreader.c valid.c include/libxml/tree.h
  include/libxml/valid.h include/libxml/xmlreader.h: working on
  DTD validation on top of xml reader interfaces. Allows to
  validate arbitrary large instances. This required some extensions
  to the valid module interface and augmenting the size of xmlID
  and xmlRef structs a bit.
* uri.c xmlregexp.c: simple cleanup.
Daniel

* Makefile.am xmlreader.c include/libxml/Makefile.am
  include/libxml/xmlreader.h:  Adding a new set of APIs based on
  the C# TextXmlReader API but converted to C. Allow to parse
  in constant memory usage, far simpler to program and explain
  than the SAX like APIs, unfinished but working.
* testReader.c: test program
