Dynamically create the kset instead of declaring it statically.

Also use the new kobj_attribute which cleans up this file a _lot_.

We don't need a "default" ktype for a kset.  We should set this
explicitly every time for each kset.  This change is needed so that we
can make ksets dynamic, and cleans up one of the odd, undocumented
assumption that the kset/kobject/ktype model has.

This patch is based on a lot of help from Kay Sievers.

Nasty bug in the block code was found by Dave Young

We need to work on cleaning up the relationship between kobjects, ksets and
ktypes.  The removal of 'struct subsystem' is the first step of this,
especially as it is not really needed at all.

Thanks to Kay for fixing the bugs in this patch.

- cluster/sys.c: make needlessly global code static
- dlm/: "extern" declarations for variables belong into header files
        (and in this case, they are already in dlmdomain.h)
