Kevin Puetz c7c526d6d0 Fix memory leak when shared libxml.dll is unloaded
When a multiple modules (process/plugins) all link to libxml2.dll
they will in fact share a single loaded instance of it.
It is unsafe for any of them to call xmlCleanupParser,
as this would deinitialize the shared state and break others that might
still have ongoing use.

However, on windows atexit is per-module (rather process-wide), so if used
*within* libxml2 it is possible to register a clean up when all users
are done and libxml2.dll is about to actually unload.

This allows multiple plugins to link with and share libxml2 without
a premature cleanup if one is unloaded, while still cleaning up if *all*
such callers are themselves unloaded.

                  XML toolkit from the GNOME project

Full documentation is available on-line at
    http://xmlsoft.org/

This code is released under the MIT Licence see the Copyright file.

To build on an Unixised setup:
   ./configure ; make ; make install
   if the ./configure file does not exist, run ./autogen.sh instead.
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.

To report bugs, follow the instructions at: 
  http://xmlsoft.org/bugs.html
