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
