To save release agent binary path per-ve we need to have some place to
store it, ve root cgroups are already linked to ve via cgroup->ve_owner

ve. Also we need to have one path per cgroup_root as it prev

This module allows to manage per-page data.
We will use it in memcg page cache limiting feature
to store additional flag on page.
We may also use this in the future in many other
circumstances (for debugging and so on).

The assumption that bm_fill_super() is not called for the second time
for CT is wrong: umount operation clears sb->s_root, which causes
vfs_get_super() to call fill_super again on the next mount.
Make bm_fill_super() handle multiple-calls corrently:
- initialize bm_data and set ve->binfmt_misc onl
Avoid several compile errors if CONFIG_VE is not defined.
