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.

This passes through the container hostname to HCS, which in Windows Server
2016 TP4 will set the container's hostname in the registry before starting
it. This will be silently ignored by TP3.

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.

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.

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

The 'deny ptrace' statement was supposed to only ignore
ptrace failures in the AUDIT log. However, ptrace was implicitly
allowed from unconfined processes (such as the docker daemon and
its integration tests) due to the abstractions/base include.
This rule narrows the definition such that it will only ignore
the failures originating inside of the container and will not
cause denials when the daemon or its tests ptrace inside processes.
Introduces positive and negative tests for ptrace /w apparmor.

Integration tests were failing due to proc filter behavior
changes with new apparmor policies.
Also include the missing docker-unconfined policy resolving
potential startup errors. This policy is complain-only so
it should behave identically to the standard unconfined policy,
but will not apply system path-based policies within containers.
