The main purpose of this patch is to remove top-level cgroups when they are remvoed from finit.conf. However, this is tricky, becasue there may still be supervised services (and children of them) running. We must postpone removal until a cgroup.events change. To make matters worse, events may arrive out-of-order, i.e. the last-child event for the parent cgroup before the sub-group. A spin-off from this patch is that we can now support arbitrarily long group names and group config. (Only applies to top-level cgroups, not run/task/services.) Limitations: - Processes in "removed" cgroups are not migrated/orphaned, the reasons are several: overhead and complexity and the fact that memory cannot be migrated - A lingering child of a moved service may prevent an old top-level cgroup from being removed.
