[libvirt] [PATCH v4 08/31] util: file: 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 variable of type virFileWrapperFdPtr is declared using VIR_AUTOPTR, the function virFileWrapperFdFree will be run automatically on it when it goes out of scope.
