Make sure an error is returned straight away if there's contention on
the underlying db file. This makes sure we don't reintroduce the issue
fixed in d21d088, and it will help detect contention in parallelized
tests if they're badly written. It effectively adds a new error mode to
the daemon, but if anyone faces this error, they should fix their
process manager.

Libnetwork provides a native Go implementation for connecting containers
The goal of libnetwork is to deliver a robust Container Network Model that provides a consistent programming interface and the required network abstractions for applications.
There are many networking solutions available to suit a broad range of use-cases. libnetwork uses a driver / plugin model to support all of these solutions while abstracting the complexity of the driver implementations by exposing a simple and consistent Network Model to users.
