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
