[xml] xmlCleanupParser() question / patch

[Aron Szabo <aron pointless hu>]

Hi!

If I use the library in a threaded program and call xmlCleanupParser() I 
can't reinitialize it.

So here's what happens:

1. xmlCleanupThreads() is called from xmlCleanupParser()
2. the global key is deleted by xmlCleanupParser() which was created by 
xmlOnceInit()

So the problem is that if I want to clear the data allocated then I 
can't use the library because it will leak memory (xmlOnceInit will not 
be called). The simplest way to solve this issue is to reset once_control.

The other way is to remove xmlCleanupThreads() from the cleanup process 
and let the user/programmer do the dirty work...
