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

[Dan Smith]

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 :)
