Adds support for the daemon to handle user namespace maps as a
per-daemon setting.
Support for handling uid/gid mapping is added to the builder,
archive/unarchive packages and functions, all graphdrivers (except
Windows), and the test suite is updated to handle user namespace daemon
rootgraph changes.

progressreader.Broadcaster becomes broadcaster.Buffered and
broadcastwriter.Writer becomes broadcaster.Unbuffered.
The package broadcastwriter is thus renamed to broadcaster.

Although having a request ID available throughout the codebase is very
valuable, the impact of requiring a Context as an argument to every
function in the codepath of an API request, is too significant and was
not properly understood at the time of the review.
Furthermore, mixing API-layer code with non-API-layer code makes the
latter usable only by API-layer code (one that has a notion of Context).
This reverts commit de41640435, reversing
changes made to 7daeecd42d.

This PR adds a "request ID" to each event generated, the 'docker events'
stream now looks like this:
```
2015-09-10T15:02:50.000000000-07:00 [reqid: c01e3534ddca] de7c5d4ca927253cf4e978ee9c4545161e406e9b5a14617efb52c658b249174a: (from ubuntu) create
```
Note the `[reqID: c01e3534ddca]` part, that's new.
Each HTTP request will generate its own unique ID. So, if you do a
`docker build` you'll see a series of events all with the same reqID.
This allow for log processing tools to determine which events are all related
to the same http request.
I didn't propigate the context to all possible funcs in the daemon,
I decided to just do the ones that needed it in order to get the reqID
into the events. I'd like to have people review this direction first, and
if we're ok with it then I'll make sure we're consistent about when
we pass around the context - IOW, make sure that all funcs at the same level
have a context passed in even if they don't call the log funcs - this will
ensure we're consistent w/o passing it around for all calls unnecessarily.

- Print the mount table as in /proc/self/mountinfo
- Do not exit prematurely when one of the ipc mounts doesn't exist.
- Do not exit prematurely when one of the ipc mounts cannot be unmounted.
- Add a unit test to see if the cleanup really works.
- Use syscall.MNT_DETACH to cleanup mounts after a crash.
- Unmount IPC mounts when the daemon unregisters an old running container.

Using @mavenugo's patch for enabling the libcontainer pre-start hook to
be used for network namespace initialization (correcting the conflict
with user namespaces); updated the boolean check to the more generic
SupportsHooks() name, and fixed the hook state function signature.

This changeset creates /dev/shm and /dev/mqueue mounts for each container under
/var/lib/containers/<id>/ and bind mounts them into the container. When --ipc:container<id/name>
is used, then the /dev/shm and /dev/mqueue of the ipc container are used instead of creating
new ones for the container.

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.

The following methods will deprecate the Copy method and introduce
two new, well-behaved methods for creating a tar archive of a resource
in a container and for extracting a tar archive into a directory in a
container.

Replaced github.com/docker/libcontainer with
github.com/opencontainers/runc/libcontaier.
Also I moved AppArmor profile generation to docker.
Main idea of this update is to fix mounting cgroups inside containers.
After updating docker on CI we can even remove dind.

This removes the exec config from the container after the command exits
so that dead exec commands are not displayed in the container inspect.
The commands are still kept on the daemon so that when you inspect the
exec command, not the container, you are still able to get it's exit
status.
This also changes the ProcessConfig to a pointer.

By convention /pkg is safe to use from outside the docker tree, for example
if you're building a docker orchestrator.
/nat currently doesn't have any dependencies outside of /pkg, so it seems
reasonable to move it there.
This rename was performed with:
```
gomvpkg -vcs_mv_cmd="git mv {{.Src}} {{.Dst}}" \
-from github.com/docker/docker/nat \
-to github.com/docker/docker/pkg/nat
```
