Commit b55cc5f4e did a shallow copy of libxl_{sdl,vnc}_info from the
domain config to the build info, which resulted in double-freeing
strings contained in the structures during cleanup, which later
resulted in a libvirtd crash. Fix by performing a deep copy of the
structure, VIR_STRDUP'ing embedded strings instead of simply copying
their pointers.
Fixes the following issue reported on the libvirt dev list

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.
