[PATCH 1/8][v2] audisp-racf plugin - Configuration and policy module files

[Klaus Heinrich Kiwi]

This patch adds the configuration files and policy module sources needed
by the plugin.

The policy is not using newer interfaces so that it can be build for
RHEL5 GA.

There is a need for two separate configuration files: one for the audit
dispatcher and another for the plugin itself.
The plugin configuration includes server and authentication information,
thus it should not be readable by anyone but root. The default queue
size is to allow event bursts avoiding events drop.
The plugin comes disabled by default.
