Add the base support for the new policy extensions. This does not bring
any additional functionality, or change current semantics.

policy->name is a substring of policy->hname, if prefix is not NULL, it will
allocted strlen(prefix) + strlen(name) + 3 bytes to policy->hname in policy_init().
use kzfree(ns->base.name) will casue memory leak if alloc_namespace() failed.

The locking for profile namespace removal is wrong, when removing a
profile namespace, it needs to be removed from its parent's list.
Lock the parent of namespace list instead of the namespace being removed.

The basic routines and defines for AppArmor policy. AppArmor policy
is defined by a few basic components.
profiles - the basic unit of confinement contain all the information
to enforce policy on a task
Profiles tend to be named after an executable that they
will attach to but this is not required.
namespaces - a container for a set of profiles that will be used
during attachment and transitions between profiles.
sids - which provide a unique id for each profile
