xfs: add xlog sysfs kobject and attribute handlers
Embed a kobject into the xfs log data structure (xlog). This creates a 'log' subdirectory for every XFS mount instance in sysfs. The lifecycle of the log kobject is tied to the lifecycle of the log. Also define a set of generic attribute handlers associated with the log kobject in preparation for the addition of attributes.
