Pull SELinux updates from Paul Moore:
 "The highlights:

   - A number of improvements to various SELinux internal data
     structures to help improve performance. We move the role
     transitions into a hash table. In the content structure we shift
     from hashing the content string (aka SELinux label) to the
     structure itself, when it is valid. This last change not only
     offers a speedup, but it helps us simplify the code some as well.

   - Add a new SELinux policy version which allows for a more space
     efficient way of storing the filename transitions in the binary
     policy. Given the default Fedora SELinux policy with the unconfined
     module enabled, this change drops the policy size from ~7.6MB to
     ~3.3MB. The kernel policy load time dropped as well.

   - Some fixes to the error handling code in the policy parser to
     properly return error codes when things go wrong"
