Add a new xen driver based on libxenlight [1], which is the primary toolstack starting with Xen 4.1.0. The driver is stateful and runs privileged only. Like the existing xen-unified driver, the libxenlight driver is accessed with xen:// URI. Driver selection is based on the status of xend. If xend is running, the libxenlight driver will not load and xen:// connections are handled by xen-unified. If xend is not running *and* the libxenlight driver is available, xen:// connections are deferred to the libxenlight driver. V6: - Address several code style issues noted by Daniel Veillard - Make drive work with xen:/// URI - Hold domain object reference while domain is injected in libvirt event loop. Race found and fixed by Markus Groß. V5: - Ensure events are unregistered when domain private data is destroyed. Discovered and fixed by Markus Groß. V4: - Handle restart of libvirtd, reconnecting to previously started domains - Rebased to current master - Tested against Xen 4.1 RC7-pre (c/s 22961:c5d121fd35c0) V3: - Reserve vnc port within driver when autoport=yes V2: - Update to Xen 4.1 RC6-pre (c/s 22940:5a4710640f81) - Rebased to current master - Plug memory leaks found by Stefano Stabellini and valgrind - Handle SHUTDOWN_crash domain death event [1] http://lists.xensource.com/archives/html/xen-devel/2009-11/msg00436.html
