c008283f8d Beam: convenience functions Listen and Connect 
These convenience functions expose a familiar face to the unknown and bizarre world of beam networking.

932149b2a7 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.

b0dfd5c5d9 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.

8dc1d8b6c0 Avoid "invalid memory address or nil pointer dereference" panic 
libcontainer.GetNamespace returns nil on FreeBSD because
libcontainer.namespaceList is empty. In this case, Namespaces#Get should
return nil instead of being panic.

6b292bf034 Support FreeBSD on pkg/system/utimes_*.go 
Implement system.LUtimesNano and system.UtimesNano. The latter might be
removed in future because it's basically same as os.Chtimes. That's why
the test is mainly focusing LUtimesNano.

db1a117450 Fix libcontainer network support on rhel6 
It seems that netlink in older kernels, including RHEL6, does not
support RTM_SETLINK with IFLA_MASTER. It just silently ignores it, reporting
no error, causing netlink.NetworkSetMaster() to not do anything yet
return no error.

We fix this by introducing and using AddToBridge() in a very similar manner
to CreateBridge(), which use the old ioctls directly.

This fixes https://github.com/dotcloud/docker/issues/4668
