Title: Add User Namespace support to libcontainer.

I have split the libcontainer changes from this PR https://github.com/dotcloud/docker/pull/6111 into this PR.
This PR depends upon this change -- https://github.com/dotcloud/docker/pull/6417

I want to get feedback on the implementation and the UI. For using this see https://github.com/dotcloud/docker/pull/6111 changes to the docker side.

The changes allow one to specify UID/GID Mappings and also the user on host that will be mapped to root within the container. The UI can be tweaked on feedback.
