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. Also, drop the redundant viralloc.h include, since that has moved from the source module into the header. When variables of type virMediatedDevicePtr and virMediatedDeviceTypePtr are declared using VIR_AUTOPTR, the functions virMediatedDeviceFree and virMediatedDeviceTypeFree, respectively, will be run automatically on them when they go out of scope.
