[GIT PULL] SELinux patches for v6.5

[Paul Moore]

Hi Linus,

We've got a number of SELinux patches for v6.5, but nothing too scary.
It is worth mentioning that there is a minor merge conflict in
security/selinux/Makefile (due to the quick fix sent during the
v6.4-rcX cycle); the proper way to resolve the conflict is to simply
take the version in this pull request.

Here is a quick summary of the changes:

- Thanks to help from the MPTCP folks, it looks like we have finally
sorted out a proper solution to the MPTCP socket labeling issue, see
the new security_mptcp_add_subflow() LSM hook.

- Fix the labeled NFS handling such that a labeled NFS share mounted
prior to the initial SELinux policy load is properly labeled once a
policy is loaded; more information in the commit description.

- Two patches to security/selinux/Makefile, the first took the
cleanups in v6.4 a bit further and the second removed the grouped
targets support as that functionality doesn't appear to be properly
supported prior to make v4.3.

- Deprecate the "fs" object context type in SELinux policies.  The fs
object context type was an old vestige that was introduced back in
v2.6.12-rc2 but never really used.

- A number of small changes that remove dead code, clean up some
awkward bits, and generally improve the quality of the code.  See the
individual commit descriptions for more information.

Thanks,
-Paul
