xen: don't let bogus packets trigger over-allocation and segfault
* src/xen/proxy_internal.c (xenProxyDomainDumpXML): An invalid packet could include a too-large "ans.len" value, which would make us allocate too much memory and then copy data from beyond the end of "ans", possibly evoking a segfault. Ensure that the value we use is no larger than the remaining portion of "ans". Also, change unnecessary memmove to memcpy (src and dest obviously do not overlap, so no need to use memmove). (xenProxyDomainGetOSType): Likewise. (xenProxyGetCapabilities): Likewise.
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.

Description
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
