[libvirt] [PATCH 0/4 v2] ivshmem support

v1 - v2: * Change attribute "model" to be a sub-element instead. NOTE: Since the invshmem server socket path is not created by QEMU, but by an external app called "ivshmem_server", It's not good to construct the socket path in libvirt with a solid rule, and force the user to figure out what the path is libvirt uses first and use that for "ivshmem_server". Thus it's the user's business to set the selinux context on the socket path so that the qemu process could be started successfully when selinux is enabled. Shawn Furrow proposed a patch more than a month ago: https://www.redhat.com/archives/libvir-list/2012-September/msg01612.html But this is a complete different implementation. Considering there could be other memory related devices in futuer, this introduces a new device model, called "memory device", instead of a specific device like "ivshmem", though only "ivshmem" is supported currently. Please refer to PATCH 1/4 for more details. CC'ed to Cam and Shawn, to see if there is advise on the documents.
