John Johansen bc4d82fb94 apparmor: fix incorrect type assignment when freeing proxies
sparse reports

poisoning the proxy->label before freeing the struct is resulting in
a sparse build warning.
../security/apparmor/label.c:52:30: warning: incorrect type in assignment (different address spaces)
../security/apparmor/label.c:52:30:    expected struct aa_label [noderef] <asn:4>*label
../security/apparmor/label.c:52:30:    got struct aa_label *<noident>

fix with RCU_INIT_POINTER as this is one of those cases where
rcu_assign_pointer() is not needed.

John Johansen 26b7899510 apparmor: add support for absolute root view based labels
With apparmor policy virtualization based on policy namespace View's
we don't generally want/need absolute root based views, however there
are cases like debugging and some secid based conversions where
using a root based view is important.

John Johansen f1bd904175 apparmor: add the base fns() for domain labels
Begin moving apparmor to using broader domain labels, that will allow
run time computation of domain type splitting via "stacking" of
profiles into a domain label vec.
