[Libvirt-cim] [PATCH 00 of 18] Updates for libcmpiutil API change

This refactors all of the necessary functions in libvirt-cim for the new API. Things only got cleaner, I think. I also found a substantial number of memory leaks in the process, which are fundamentally fixed by the new API which I think is a validation of it as "the right thing to do". All required changes should have been easily spotted by the compiler, but some testing would be good. Tip: To find the leaks, note every time we convert a variable from char * to const char * and don't remove a subsequent free() call :)
