  The problem is that we can't really add an xmlInitParser() to every
single call exported by libxml2 (1500+) and since more and more programs
or library code is intended to be multithreaded, it is really a good
habit to initializat the library (in the main thread or at library init
time).
  We added such call to the most used entry points related to parsing
but indeed xmlRead* and xmlCtxtRead* could get those too, as well as
their html counterparts (htmlReadIO calls it nut not others !)

  So it's a bit messy, but adding it to all xmlRead* xmlCtxtRead*
and html equivalents sounds a fair request, even if 'bug' might be
a bit too strong :-)

  Commited locally, I will push later when I get access,

   Pushed now ...

  thanks,

Daniel
