[libvirt] Resubmission #2: [PATCH 2/3] sVirt AppArmor security driver

[PATCH 2] patch_2_apparmor_driver.patch (updated and merged into one patch based on prior feedback): - Updates src/security.c for AppArmor - Adds security_apparmor.c, security_apparmor.h, virt-aa-helper.c and updates po/POTFILES.in. virt-aa-helper.c is a new binary which is used exclusively by the AppArmor security driver to manipulate AppArmor. - Adds tests for virt-aa-helper and the security driver. secaatest.c is identical to seclabeltest.c except it initializes the 'apparmor' driver instead of 'selinux'. These tests are integrated into 'make check' and pass. - Updates configure.in, Makefile.am, src/Makefile.am, tests/Makefile.am, and tools/Makefile.am for AppArmor. It is based on and should operate the same as the SELinux configuration.
