[SECMARK]: Add new flask definitions to SELinux

Secmark implements a new scheme for adding security markings to
packets via iptables, as well as changes to SELinux to use these
markings for security policy enforcement.  The rationale for this
scheme is explained and discussed in detail in the original threads:

 http://thread.gmane.org/gmane.linux.network/34927/
 http://thread.gmane.org/gmane.linux.network/35244/

Examples of policy and rulesets, as well as a full archive of patches
for iptables and SELinux userland, may be found at:

http://people.redhat.com/jmorris/selinux/secmark/

The code has been tested with various compilation options and in
several scenarios, including with 'complicated' protocols such as FTP
and also with the new generic conntrack code with IPv6 connection
tracking.

This patch:

Add support for a new object class ('packet'), and associated
permissions ('send', 'recv', 'relabelto').  These are used to enforce
security policy for network packets labeled with SECMARK, and for
adding labeling rules.
