[xml] Patch to allow parsing files with pathes containing unicode characters on windows...

[Roland Schwingel <Roland Schwingel onevision com>]

Hi... 

First I want to say, libxml2 rocks! I use it very very often and it is
very reliable and fast. Thank you all! 

But there is a small problem when I use it on windows... I also often have
files with unicode characters in 
their names. These can at present not directly be loaded by libxml2 (on
windows). 

While it is possible to read a file to memory using native OS calls and
then passing the content to xmlParseMemory() 
this still causes overhead especially if you want to parse real big files.
So I made a small change to xmlIO.c 
allowing libxml2 to read those files directly on windows. This patch is
attached to this email. 

The API of libxml2 is utf-8 based (from what I understand - and working
with pathes containing 
uft-8 characters works very well on Linux and Mac). 

So I added some windows specific code to xmlIO.c that converts an utf8
string to windows wide character. 
This recoded path will then be used to open a file using windows wide character
api for reading/writing. 
That small and simple. 

I am using this patch for quite a while now and it serves it's task very
well. I don't know much about the 
conventions regarding code writing for libxml2, but I tried as much as
possible to not completely break every rule... 

I hope you find this patch as useful as I do, and you can incorporate this
patch in one of the next versions 
of libxml2. 

Thanks, 

Roland
