If no 'security_driver' config option was set, then the code
just loaded the 'dac' security driver. This is a regression
on previous behaviour, where we would probe for a possible
security driver. ie default to SELinux if available.
This changes things so that it 'security_driver' is not set,
we once again do probing. For simplicity we also always
create the stack driver, even if there is only one driver
active.
The desired semantics are:
- security_driver not set
-> probe for selinux/apparmour/nop
-> auto-add DAC driver
- security_driver set to a string
-> add that one driver
-> auto-add DAC driver
- security_driver set to a list
-> add all drivers in list
-> auto-add DAC driver
It is not allowed, or possible to specify 'dac' in the
security_driver config param, since that is always
enabled.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
