    Python bindings: DOM casts everything to xmlNode

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.

To build on an Unixised setup:
   ./configure ; make ; make install
To build on Windows:
   see instructions on win32/Readme.txt

To assert build quality:
   on an Unixised setup:
      run make tests
   otherwise:
       There is 3 standalone tools runtest.c runsuite.c testapi.c, which
       should compile as part of the build or as any application would.
       Launch them from this directory to get results, runtest checks 
       the proper functionning of libxml2 main APIs while testapi does
       a full coverage check. Report failures to the list.
