3.3-3.14: access permission filesystem

I finally came around updating the accessfs module to Linux 3.14.

This patch adds a new permission managing file system. Furthermore, it adds two modules, which make use of this file system.

One module allows granting capabilities based on user-/groupid. The second module allows to grant access to lower numbered ports based on user-/groupid, too.

Changes:
- Update up to 3.14
- Included patches from Bart van der Meulen
+ register accessfs with the LSM system
+ clear I_NEW flag to prevent busy inodes on umount

The patches are available at:
<http://www.olafdietsche.de/linux/accessfs/>

and at github

<https://github.com/olafdietsche/linux-accessfs>

in the accessfs branch.
