kernel: enable AppArmor by default

AppArmor only requires a few patches to the 3.2 and 3.4 kernels in order
to work properly (with the minor catch grsecurity -stable includes the
3.2 patches.) This adds them to the kernel builds by default, removes
features.apparmor (since it's always true) and makes it the default MAC
system.

+Subject: [PATCH 3/3] AppArmor: Allow dfa backward compatibility with broken
+ userspace
+
+The apparmor_parser when compiling policy could generate invalid dfas
+that did not have sufficient padding to avoid invalid references, when
+used by the kernel.  The kernels check to verify the next/check table
+size was broken meaning invalid dfas were being created by userspace
+and not caught.
+
+To remain compatible with old tools that are not fixed, pad the loaded
+dfas next/check table.  The dfa's themselves are valid except for the
+high padding for potentially invalid transitions (high bounds error),
+which have a maximimum is 256 entries.  So just allocate an extra null filled
+256 entries for the next/check tables.  This will guarentee all bounds
+are good and invalid transitions go to the null (0) state.

+From a94d5e11c0484af59e5feebf144cc48c186892ad Mon Sep 17 00:00:00 2001
+From: John Johansen <john.johansen@canonical.com>
+Date: Wed, 16 May 2012 10:58:05 -0700
+Subject: [PATCH 3/3] UBUNTU: SAUCE: apparmor: Add the ability to mediate
+ mount
+
+Add the ability for apparmor to do mediation of mount operations. Mount
+rules require an updated apparmor_parser (2.8 series) for policy compilation.
+
+The basic form of the rules are.
+
+  [audit] [deny] mount [conds]* [device] [ -> [conds] path],
+  [audit] [deny] remount [conds]* [path],
+  [audit] [deny] umount [conds]* [path],
+  [audit] [deny] pivotroot [oldroot=<value>] <path>
+
+  remount is just a short cut for mount options=remount
+
+  where [conds] can be
+    fstype=<expr>
+    options=<expr>
+
+Example mount commands
+  mount,		# allow all mounts, but not umount or pivotroot
+
+  mount fstype=procfs,  # allow mounting procfs anywhere
+
+  mount options=(bind, ro) /foo -> /bar,  # readonly bind mount
+
+  mount /dev/sda -> /mnt,
+
+  mount /dev/sd** -> /mnt/**,
+
+  mount fstype=overlayfs options=(rw,upperdir=/tmp/upper/,lowerdir=/) -> /mnt/
+
+  umount,
+
+  umount /m*,
+
+See the apparmor userspace for full documentation
