John Johansen 637f688dc3 apparmor: switch from profiles to using labels on contexts
Begin the actual switch to using domain labels by storing them on
the context and converting the label to a singular profile where
possible.

John Johansen cf797c0e5e apparmor: convert to profile block critical sections
There are still a few places where profile replacement fails to update
and a stale profile is used for mediation. Fix this by moving to
accessing the current label through a critical section that will
always ensure mediation is using the current label regardless of
whether the tasks cred has been updated or not.

John Johansen aa9a39ad8f apparmor: convert change_profile to use fqname later to give better control
Moving the use of fqname to later allows learning profiles to be based
on the fqname request instead of just the hname. It also allows cleaning
up some of the name parsing and lookup by allowing the use of
the fqlookupn_profile() lib fn.

John Johansen 47f6e5cc73 apparmor: change op from int to const char *
Having ops be an integer that is an index into an op name table is
awkward and brittle. Every op change requires an edit for both the
op constant and a string in the table. Instead switch to using const
strings directly, eliminating the need for the table that needs to
be kept in sync.

John Johansen 63e2b42377 AppArmor: userspace interfaces
The /proc/<pid>/attr/* interface is used for process introspection and
commands.  While the apparmorfs interface is used for global introspection
and loading and removing policy.

The interface currently only contains the files necessary for loading
policy, and will be extended in the future to include sysfs style
single per file introspection inteface.

The old AppArmor 2.4 interface files have been removed into a compatibility
patch, that distros can use to maintain backwards compatibility.
