[libvirt] [PATCH v1 04/32] util: macaddr: 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. Also, drop the redundant
viralloc.h include, since that has moved from the source module into
the header.

When a variable of type virMacAddrPtr is declared using VIR_AUTOPTR,
the function virMacAddrFree will be run automatically on it when it
goes out of scope.
