Daniel Veillard 675464b183 Fix crash on events due to allocation errors 
remoteRelayDomainEventBlockJob, remoteRelayDomainEventIOError,
remoteRelayDomainEventIOErrorReason and remoteRelayDomainEventGraphics
were using const string directly in rpc structure, before calling
remoteDispatchDomainEventSend(). But that routine now frees up all
the pointed allocated memory from the rpc structure and we end up
with a double free.
This now strdup() all the strings passed and provide mem_error goto
labels to be used when an allocation error occurs.
Note that the cleanup isn't completely finished because all relaying
function also call make_nonnull_domain() which also allocate a string
and never handle the error case. This patches doesn't try to address
this as this is only error correctness a priori and touches far more
functions in this module:

* daemon/remote.c: fix string allocations and memory error handling
  for remoteRelayDomainEventBlockJob, remoteRelayDomainEventIOError,
  remoteRelayDomainEventIOErrorReason and remoteRelayDomainEventGraphics

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
