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

[Sukrit Bhatnagar <skrtbhtngr@xxxxxxxxx>]

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.
