For graceful restart case it was done when the container was brought
down. But for ungraceful cases, the persistence is missing for nw
connect

Instead of using `MNT_DETACH` to unmount the container's mqueue/shm
mounts, force it... but only on daemon init and shutdown.
This makes sure that these IPC mounts are cleaned up even when the
daemon is killed.

When a container restarts after a ungraceful daemon restart, first
cleanup any unclean sandbox before trying to allocate network resources.

Since #15862, containers fail to start when started with --ipc=host if
/dev/mqueue is not present. This change causes docker to create
container-local mounts for --ipc=host containers as well as in the
default case.

It is possible that network files do not exist, especially in the case
of `--net=host` where a host OS (like CoreOS) does not use certain
standard network files. This patch verifies that the source file of a
network mount point exists before adding it to the list of mount points
for bind mounting from the container's metadata directory.

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.

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

* Thanks to the Default gateway service in libnetwork, we dont have to add
containers explicitly to secondary public network. This is handled
automatically regardless of the primary network driver.
* Fixed the URL convention for kv-store to be aligned with the upcoming
changes to discovery URL
* Also, in order to bring consistency between external and internal network
drivers, we moved the driver configs via controller Init.

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.
