Hooray for 2.6.34 ALIGN bug still biting.
libxt_gradm.c:84: warning: implicit declaration of function 'ALIGN'
libxt_gradm.c:84: error: initializer element is not constant
libxt_gradm.c:84: error: (near initialization for 'gradm_mt_reg.size')
This patch adds a module which is useful to users of grsecurity's RBAC
system. It matches packets based on whether RBAC is enabled or
disabled.

This [xt_gradm.c] is part of the grsecurity patch which not only adds
the Xtables code, but also the RBAC code. Without the entire RBAC
stuff, xt_gradm does not make sense and so it is included with the
grsecurity patch to the kernel, and not this patch to Xtables-addons.

The idea here is that when the RBAC rulesets are not being enforced,
the system is more vulnerable and the user wants stricter firewall
rules. When RBAC is being enforced, one can relax the firewall and
access to services which are now better protected. In practice this
usually means allowing only access to some trusted IP(s) on boot
before RBAC is turned on.
