[Libvir] Lxc driver patch

Patch against CVS version, it tries to avoid 2 issues: - problem with global data settings when loading of the driver got interrupted. Check more NULLs and reset to NULL, i was getting crashes when running the regression tests and the /etc/libvirtd/lxc was not accessible. - avoid trying to open the driver if not running as root, that's not a problem in normal case because the daemon runs as root, but when running 'make check' as a normal user libvirtd is run as an user and compiling the lxc driver in would break the regression tests Dave could you double-check this, hopefully it has no side effect ?
