Instead of mutating and reverting, just create a copy and pass the copy
around.
Add a unit test for builder dispatcher.run
Fix two test failures
Fix image history by adding a CreatedBy to commit options. Previously the
createdBy field was being created by modifying a reference to the runConfig that
was held from when the container was created.
Fix a test that expected a trailing slash. Previously the runConfig was being
modified by container create. Now that we're creating a copy of runConfig
instead of sharing a reference the runConfig retains the trailing slash.

The daemon config for defaulting to no-new-privileges for containers was
added in d7fda019bb7e24f42f8ae1ddecb3fd52df3c48bf, but somehow we
managed to omit the flag itself, but also documented the flag.
This just adds the actual flag.

RH now provides `container-selinux` which provides everything we need
for docker's selinux policy. Rely on `container-selinux` where
available, and `docker-engine-selinux` when not.
This still builds the `docker-engine-selinux` package and presumably
makes it available, but is no longer a requirement in the
`docker-engine` package preferring `container-selinux` instead.
`container-selinux` is available on fedora24, however the version that
is available does not set the correct types on the `dockerd` binary. We
can use `container-selinux` and just supplement that with some of our
own policy, but for now just keep using `docker-engine-selinux` as is.

Just a small grammatical correction, but it is unnecessary to repeat "to," after the colon, and deleting it makes the format of the list more consistent and readable.

Container state counts are used for reporting in the `/info` endpoint.
Currently when `/info` is called, each container is iterated over and
the containers 'StateString()' is called. This is not very efficient
with lots of containers, and is also racey since `StateString()` is not
using a mutex and the mutex is not otherwise locked.
We could just lock the container mutex, but this is proven to be
problematic since there are frequent deadlock scenarios and we should
always have the `/info` endpoint available since this endpoint is used
to get general information about the docker host.
Really, these metrics on `/info` should be deprecated. But until then,
we can just keep a running tally in memory for each of the reported
states.

This makes sure that multiple users of MountPoint pointer can
mount/unmount without affecting each other.
Before this PR, if you run a container (stay running), then do `docker
cp`, when the `docker cp` is done the MountPoint is mutated such that
when the container stops the volume driver will not get an Unmount
request. Effectively there would be two mounts with only one unmount.

if docker exec exit and at the same the the container is pause,
there could be a chance the `docker exec exit` will fail
```
$ docker exec -ti 388c7f47a06c sh
/ # exit
Error response from daemon: Container 388c7f47a06cce0856266ffd56a2ce2901689ca7a6b9cd741b37652418448f2b is paused, unpause the container before exec
```
To reproduce this error easilly, we can add a sleep in `containerPause`

When there is an error unmounting a local volume, it is still possible
to call `Remove()` on the volume causing removal of the mounted
resources which is generally not desirable.
This ensures that resources are unmounted before attempting removal.
