[PATCH] libxl: open libxl log stream with libvirtd log_level

[Jim Fehlig <jfehlig@xxxxxxxx>]

Instead of a hardcoded DEBUG log level, use the overall
daemon log level specified in libvirtd.conf when opening
a log stream with libxl. libxl is very verbose when DEBUG
log level is set, resulting in huge log files that can
potentially fill a disk. Control of libxl verbosity should
be placed in the administrator's hands.
