  Adding a new set of APIs based on the C# TextXmlReader API but converted
  
  * 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
