The practice of buffering to a tempfile during a pushing contributes massively
to slow V2 push performance perception. The protocol was actually designed to
avoid precalculation, supporting cut-through data push. This means we can
assemble the layer, calculate its digest and push to the remote endpoint, all
at the same time.
This should increase performance massively on systems with slow disks or IO
bottlenecks.

This fixes two problems:
1. docker run --device /dev/sda:rw ubuntu bash doesn't work
2. --device /dev/zero:/dev/noro:ro doesn't show clear error message,
but fail when writing to cgroup file.

Docker ps default format should not take precedence over cli flags.
This happens effectively for other flags except `-q`.
We need to let the cli to set the format as table to print the
expected output with `-q`.

Changing vendor/src/github.com/docker/libnetwork to match lindenlab/libnetwork custom-host-port-ranges-1.7 branch
The bool logic around setting up the TTY ended up getting flipped
accidentally.
Also added a test for exec with TTY.

Introduce a write denial for files at the root of /proc.
This prohibits root users from performing a chmod of those
files. The rules for denials in proc are also cleaned up,
making the rules better match their targets.
Locally tested on:
- Ubuntu precise (12.04) with AppArmor 2.7
- Ubuntu trusty (14.04) with AppArmor 2.8.95
