[Qemu-devel] QEmu: support disk filenames with comma

[Crístian Viana]

Hi!

This patch fixes RHBZ #801036 adding support to filenames with comma using 
QEmu. As this is my first patch to libvirt, I'm not completely sure if I should 
have also changed other parts of the code, or if I have used the wrong memory 
allocation functions/macros, or if I shouldn't have created a separate commit 
to add my name to the AUTHORS file... :-)

I also need to make it clear that this patch only fixes the problem in the 
"libvirt data -> QEmu args" way (e.g., when QEmu reads an XML file to start 
QEmu, or when using virsh domxml-to-native). The other way, "QEmu args -> 
libvirt data" is *not* implemented (e.g., virsh domxml-from-native). I would 
like to know if I'm going in the right way so I can continue working on this 
patch, and if that half of the feature is also needed.

Any feedback is welcome, thanks!

Best regards,
Crístian.
