[libvirt] libvirt-php and xpath function from libxml2

[Vasiliy Tolstov]

Hi! I'm test under high load some libvirt-php xpath based function and
big memory leak under each function call. I'm try to patch libvirt-php
to free some values via xmlFree , but this is not solve leaks.
Do we realy need this function? As i see when i'm use plain libvirt
function and use returned xml with internal php functions that works
with xml and xpath, i'm not get memory leaks.

So does we really need it?
