[PATCH 00/17] conf: Fix and prevent uninitialized memory use with new virXMLProp* helpers

Compilers aren't able to see that the value passed via a pointer from the new virXMLProp helpers may be uninitialized in certain cases. Fix 3 such cases, prepare the code and then ensure that the new virXMLProp* helpers always initialize the memory.
