Tim Hockin d25aa3cee7 Don't set the MTU for loopback interfaces. 
Setting the MTU for loopback has a huge performance impact on intra-container
traffic. The loopback interface is not an ethernet interface and does not need
the same limit. with this change I see a 4x speedup for loopback throughput.

Vishnu Kannan 9253412ee1 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

Vishnu Kannan b50266335e 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.
