[PATCH] Capture selinux subject/object context information.
This patch extends existing audit records with subject/object context information. Audit records associated with filesystem inodes, ipc, and tasks now contain SELinux label information in the field "subj" if the item is performing the action, or in "obj" if the item is the receiver of an action. These labels are collected via hooks in SELinux and appended to the appropriate record in the audit code. This additional information is required for Common Criteria Labeled Security Protection Profile (LSPP).
