This change include filter `name` and `driver`,
and also update related docs to reflect that filters usage.

Instead of implementing refcounts at each graphdriver, implement this in
the layer package which is what the engine actually interacts with now.
This means interacting directly with the graphdriver is no longer
explicitly safe with regard to Get/Put calls being refcounted.
In addition, with the containerd, layers may still be mounted after
a daemon restart since we will no longer explicitly kill containers when
we shutdown or startup engine.
Because of this ref counts would need to be repopulated.

Now that the namespace sharing code via runc is vendored with the
containerd changes, we can disable the restrictions on container to
container net and IPC namespace sharing when the daemon has user
namespaces enabled.

This allows a user to specify explicitly to enable
automatic copying of data from the container path to the volume path.
This does not change the default behavior of automatically copying, but
does allow a user to disable it at runtime.

This adds support for the passthrough on build, push, login, and search.
Revamp the integration test to cover these cases and make it more
robust.
Use backticks instead of quoted strings for backslash-heavy string
contstands.

This cleans up some of the use of the filepoller which makes reading
significantly more robust and gives fewer changes to fallback to the
polling based watcher.
In a lot of cases, if the file was being rotated while we were adding it
to the watcher, it would return an error that the file doesn't exist and
would fallback.
In some cases this fallback could be triggered multiple times even if we
were already on the fallback/poll-based watcher.
It also fixes an open file leak caused by not closing files properly on
rotate, as well as not closing files that were read via the `tail`
function until after the log reader is completed.
Prior to the above changes, it was relatively simple to cause the log
reader to error out by having quick rotations, for example:
```
$ docker run --name test --log-opt max-size=10b --log-opt max-files=10
-d busybox sh -c 'while true; do usleep 500000; echo hello; done'
$ docker logs -f test
```
After these changes I can run this forever without error.
Another fix removes 2 `os.Stat` calls when rotating files. The stat
calls are not needed since we are just calling `os.Rename` anyway, which
will in turn also just produce the same error that `Stat` would.
These `Stat` calls were also quite expensive.
Removing these stat calls also seemed to resolve an issue causing slow
memory growth on the daemon.

so that the user knows what's not in the container but should be.
Its not always easy for the user to know what exact command is being run
when the 'docker run' is embedded deep in something else, like a Makefile.
Saw this while dealing with the containerd migration.
