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.

Alias virString to (char *) so that the new cleanup macros
can be used for a list of strings (char **).

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.
