[libvirt] [PATCH v1 07/40] util: hash: 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 variables of type virHashTablePtr are declared using
VIR_AUTOPTR, the function virHashFree will be run
automatically on it when it goes out of scope.
