[libvirt] [PATCH v4 22/31] util: bitmap: 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 virBitmapPtr is declared using
VIR_AUTOPTR, the function virBitmapFree will be run
automatically on it when it goes out of scope.
