So we don't print those <no value> in the client and we don't fail
executing inspect templates with API field names.
Make sure those fields are initialized as empty slices when
a container is loaded from disk and their values are nil.

The LXC driver was deprecated in Docker 1.8.
Following the deprecation rules, we can remove a deprecated feature
after two major releases. LXC won't be supported anymore starting on Docker 1.10.

Generate a hash chain involving the image configuration, layer digests,
and parent image hashes. Use the digests to compute IDs for each image
in a manifest, instead of using the remotely specified IDs.
To avoid breaking users' caches, check for images already in the graph
under old IDs, and avoid repulling an image if the version on disk under
the legacy ID ends up with the same digest that was computed from the
manifest for that image.
When a calculated ID already exists in the graph but can't be verified,
continue trying SHA256(digest) until a suitable ID is found.
"save" and "load" are not changed to use a similar scheme. "load" will
preserve the IDs present in the tar file.

* Moving Network Remote APIs out of experimental
* --net can now accept user created networks using network drivers/plugins
* Removed the experimental services concept and --default-network option
* Neccessary backend changes to accomodate multiple networks per container
* Integration Tests

- The build-time variables are passed as environment-context for command(s)
run as part of the RUN primitve. These variables are not persisted in environment of
intermediate and final images when passed as context for RUN. The build environment
is prepended to the intermediate continer's command string for aiding cache lookups.
It also helps with build traceability. But this also makes the feature less secure from
point of view of passing build time secrets.
- The build-time variables also get used to expand the symbols used in certain
Dockerfile primitves like ADD, COPY, USER etc, without an explicit prior definiton using a
ENV primitive. These variables get persisted in the intermediate and final images
whenever they are expanded.
- The build-time variables are only expanded or passed to the RUN primtive if they
are defined in Dockerfile using the ARG primitive or belong to list of built-in variables.
HTTP_PROXY, HTTPS_PROXY, http_proxy, https_proxy, FTP_PROXY and NO_PROXY are built-in
variables that needn't be explicitly defined in Dockerfile to use this feature.

Allow to set the signal to stop a container in `docker run`:
- Use `--stop-signal` with docker-run to set the default signal the container will use to exit.

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.

It may happen that host system settings are changed while the daemon is running.
This will cause errors at libcontainer level when starting a container with a
particular hostConfig (e.g. hostConfig with memory swappiness but the memory
cgroup was umounted).
This patch adds an hostConfig check on container start to prevent the daemon
from even calling libcontainer with the wrong configuration as we're already
doing on container's creation).
