Message : hack based on Arjan van de Ven suggestion to reduce ELF footprint and * elfgcchack.h doc/elfgcchack.xsl libxml.h: hack based on Arjan van de Ven suggestion to reduce ELF footprint and generated code. Based on aliasing of libraries function to generate direct call instead of indirect ones * doc/libxml2-api.xml doc/Makefile.am doc/apibuild.py: added automatic generation of elfgcchack.h based on the API description, extended the API description to show the conditionals configuration flags required for symbols. * nanohttp.c parser.c xmlsave.c include/libxml/*.h: lot of cleanup * doc/*: regenerated the docs.

 *
 * Exclusive XML Canonicazation
 * http://www.w3.org/TR/xml-exc-c14n
 *
 * Canonical form of an XML document could be created if and only if
 *  a) default attributes (if any) are added to all nodes
 *  b) all character and parsed entity references are resolved
 * In order to achive this in libxml2 the document MUST be loaded with 
 * following global setings:
 *    
 *    xmlLoadExtDtdDefaultValue = XML_DETECT_IDS | XML_COMPLETE_ATTRS;
 *    xmlSubstituteEntitiesDefault(1);
 *
 * or corresponding parser context setting:
 *    xmlParserCtxtPtr ctxt;
 *    
 *    ... 
 *    ctxt->loadsubset = XML_DETECT_IDS | XML_COMPLETE_ATTRS;
 *    ctxt->replaceEntities = 1;
 *    ...
