[GIT PULL] AppArmor fixes for 4.11

[John Johansen]

Hi James,

This is a set of bug fixes, a few additions to apparmorfs policy
introspection, a lot of code refactoring, and cleanups taking care of
most of the compiler and sparse warnings.

It does not implement new mediation or change the behavior of current
upstream apparmor mediation but provides a base to begin doing RFCs
for updated apparmor mediation.

Thanks,
-John
