We are able to safe some space when we assign the subsystem
IDs at compile time. Instead of allocating per cgroup
cgroup->subsys[CGROUP_SUBSYS_COUNT] where CGROUP_SUBSYS_COUNT is
always 64, we allocate 12 + 1 at max (at this point there are 12
subsystem). The additinal one is the price we have to pay to
distinguish between builtin and module subsystems.

We should only access task_cls_classid() and task_netprioidx()
if the subsystem is ready to be used using jump labels for this.

I think I want to like this patch but it's kinda confusing to review.
Is there any reasonable way that you can split the core changes from
net_cls ones?

Thanks.
