Implemented native libxml2 XML API for dmidecode

To use this API, you need to import dmidecodeXML.  This is a wrapper class for
the internal XML API which has been implemented.  In addition, you might also
want to import libxml2 as well.

dmidecodeXML::QuerySection(<string>)
Valid section strings can be found in the pymap.xml file, in the <GroupMapping>
tag section.

dmidecodeXML::TypeId(<integer between 0-255>)
Valid values should match the DMI/SMBIOS specification.

dmidecodeXML::SetResultType(resultType)
Result type can be either  dmidecodeXML.DMIXML_NODE or dmidecodeXML.DMIXML_DOC

----------------------------------------------------------
import libxml2
import dmidecodeXML

dmixml = dmidecodeXML.dmidecodeXML()

section_nodes = dmixml.QuerySection('processor')

dmixml.SetResultType(dmidecodeXML.DMIXML_DOC)

typeid_doc =  dmixml.QueryTypeId(0x10)

dmixml.SetResultType(dmidecodeXML.DMIXML_NODE)

typeid_doc.saveFormatFileEnc("-", "UTF-8", 1)
