1. Added a basic version of network stats inside network package.
...
2. Introducing a new checkpoint file 'network.stats' which will contain the network runtime information (veth interface names for now).
3. Adding network stats to 'nsinit stats'.
4. Added a libcontainer Stats API to get both network and cgroup stats

Updated libcontainer subpackage dependencies. Most subpackages now do not depend on their parent ('libcontainer') package. 'namespaces' and 'nsinit' still do.
...
'namespaces' need to refactored a bit more to move the API part of it to 'libcontainer' package and keep the namespace specific code inside that package.
This change is not expected to break docker.

Fix invalid fd race
...
Sometimes I was getting:
2014/06/13 13:47:24 finalize namespace drop bounding set read /proc/1/status: bad file descriptor
This happens when applying the capabilities, and the code that
reads the current caps opens /proc/1/status and then reads some data from it.
But during this it gets a EBADFD error.
The problem is that FinalizeNamespace() closes all FDs before applying
the caps, and if a GC then happens after /proc/1/status is opened but
before reading from the fd, then an old os.File finalizer may close the
already closed-and-reused fd, wreaking havoc.
We fix this by instead of closing the FDs we mark them close-on-exec
which guarantees that they will be closed when we do the final
exec into the container.
