Solomon Hykes 5957e6b385 Beam: a simple stream-oriented communication protocol for distributed systems. 
This patch includes a stripped down implementation with a bare minimum
unix socket transport. It relies on fd passing for stream multiplexing.

The purpose of this first patch is to allow implementation of dynamic
linking, which will allow advanced service discovery.

Michael Crosby 5f4bc4f916 Use apparmor_parser directly 
The current load script does alot of things.  If it does not find the
parser loaded on the system it will just exit 0 and not load the
profile.  We think it should fail loudly if it cannot load the profile
and apparmor is enabled on the system.

libcontainer.GetNamespace returns nil on FreeBSD because
