[libvirt] [PATCH v4 18/31] util: json: define cleanup function using VIR_DEFINE_AUTOPTR_FUNC

[Sukrit Bhatnagar]

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 variable of type virJSONValuePtr is declared using
VIR_AUTOPTR, the function virJSONValueFree will be run
automatically on it when it goes out of scope.
