[xml] Delphi bindings for libxml2

[<Eric Zurcher csiro au>]

Hello all,

It is now almost exactly 2 years since the last update of Petr Kozelka's Pascal units for accessing libxml2 
and libxslt(available at http://sourceforge.net/projects/libxml2-pas). Those units corresponded to release 
2.5.10 of libxml2. Since then, there have been a number of significant additions to the libxml2 API, such as 
the addition of the SAX2 parser.

I make extensive use of libxml2 in several of my Delphi applications, and wanted to be able to make use of 
the faster SAX2 code, so I thought I'd try updating the bindings on my own. I first tried using h2pas, but 
found that it didn't work as well as I had hoped (perhaps a result of my inexperience in its use). As an 
alternative, I put together an XSLT transformation to generate the bindings from libxml2-api.xml (and its 
libxslt counterparts), rather than from the *.h files. This approach seems to have worked well, with the 
output of the transformation requiring only a tiny bit of manual editing. 

I have tried several times to contact Petr to see whether he would like to incorporate my binding into his 
libxml2-pas project on sourceforge, but I have received no response from him. I am writing now to see whether 
anyone else is interested this code, or in providing a "home" for it so that it can be distributed 
(preferably under the terms of the MIT license) to any who wish to use it.
