cgroup: make CFTYPE_ONLY_ON_DFL and CFTYPE_NO_ internal to cgroup core
cgroup now distinguishes cftypes for the default and legacy hierarchies more explicitly by using separate arrays and CFTYPE_ONLY_ON_DFL and CFTYPE_INSANE should be and are used only inside cgroup core proper. Let's make it clear that the flags are internal by prefixing them with double underscores. CFTYPE_INSANE is renamed to __CFTYPE_NOT_ON_DFL for consistency. The two flags are also collected and assigned bits >= 16 so that they aren't mixed with the published flags. v2: Convert the extra ones in cgroup_exit_cftypes() which are added by revision to the previous patch.
