[libvirt] [PATCH 1/5] Remove bogus const annotations to hash iterator

["Daniel P. Berrange" <berrange@xxxxxxxxxx>]

Most of the hash iterators need to modify either payload of
data args. The const annotation prevents this.

* src/util/hash.h, src/util/hash.c: Remove const-ness from
  virHashForEach/Iterator
* src/xen/xm_internal.c: Remove bogus casts
