Python bindings: DOM casts everything to xmlNode

Browse Source 
I noticed another issue with Python bindings of libxml: the access methods do
not cast the pointers to specific classes such as xmlDtd, xmlEntityDecl, etc.
For example, with the following document:

<?xml version="1.0"?>
<!DOCTYPE root [<!ELEMENT root EMPTY>]>
<root/>

the following script:

import libxml2
doc = libxml2.readFile("c.xml", None, libxml2.XML_PARSE_DTDLOAD)
print repr(doc.children)

prints:

<xmlNode (root) object at 0xb74963ec>

With properly cast nodes, it outputs the following:

<xmlDtd (root) object at 0xb746352c>

The latter object (xmlDtd) enables one to use DTD-specific methods such as
debugDumpDTD(), copyDTD(), and so on.
