[libvirt] [PATCH v3 07/35] util: string: define cleanup function using VIR_DEFINE_AUTOPTR_FUNC

Using the new VIR_DEFINE_AUTOPTR_FUNC macro defined in src/util/viralloc.h, define a new wrapper around an existing cleanup function which will be called when a variable declared with VIR_AUTOPTR macro goes out of scope. When a list of strings (virString *) is declared using VIR_AUTOPTR, the function virStringListFree will be run automatically on it when it goes out of scope.
