When manually stopping a container with a restart-policy, the container
would show as "restarting" in `docker ps` whereas its actual state
is "exited".
Stopping a container with a restart policy shows the container as "restarting"
docker run -d --name test --restart unless-stopped busybox false
docker stop test
docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
7e07409fa1d3 busybox "false" 5 minutes ago Restarting (1) 4 minutes ago test
However, inspecting the same container shows that it's exited:
docker inspect test --format '{{ json .State }}'
{
"Status": "exited",
"Running": false,
"Paused": false,
"Restarting": false,
"OOMKilled": false,
"Dead": false,
"Pid": 0,
"ExitCode": 1,
"Error": "",
"StartedAt": "2019-02-14T13:26:27.6091648Z",
"FinishedAt": "2019-02-14T13:26:27.689427Z"
}
And killing the container confirms this;
docker kill test
Error response from daemon: Cannot kill container: test: Container 7e07409fa1d36dc8d8cb8f25cf12ee1168ad9040183b85fafa73ee2c1fcf9361 is not running

Older API clients did not use a pointer for `PidsLimit`, so
API requests would always send `0`, resulting in any previous
value to be reset after an update:
Before this patch:
(using a 17.06 Docker CLI):
```bash
docker run -dit --name test --pids-limit=16 busybox
docker container inspect --format '{{json .HostConfig.PidsLimit}}' test
16
docker container update --memory=100M --memory-swap=200M test
docker container inspect --format '{{json .HostConfig.PidsLimit}}' test
0
docker container exec test cat /sys/fs/cgroup/pids/pids.max
max
```
With this patch applied:
(using a 17.06 Docker CLI):
```bash
docker run -dit --name test --pids-limit=16 busybox
docker container inspect --format '{{json .HostConfig.PidsLimit}}' test
16
docker container update --memory=100M --memory-swap=200M test
docker container inspect --format '{{json .HostConfig.PidsLimit}}' test
16
docker container exec test cat /sys/fs/cgroup/pids/pids.max
16
```

Some tests were skipped if the local daemon did not have
experimental features enabled; at the same time, some tests
unconditionally created a new (experimental) daemon, even if
the local daemon already had experimental enabled.
This patch;
- Checks if the "testEnv" is an experimental Linux daemon
- If not, and the daemon is running locally; spin up a new
experimental daemon to be used during the test.

Due to a bug in Golang (github.com/golang#27640), the "character device"
bit was omitted when checking file-modes with `os.ModeType`.
This bug was resolved in Go 1.12, but as a result, graphdrivers
would no longer recognize "device" files, causing pulling of
images that have a file with this filemode to fail;
failed to register layer:
unknown file type for /var/lib/docker/vfs/dir/.../dev/console
The current code checked for an exact match of Modes to be set. The
`os.ModeCharDevice` and `os.ModeDevice` bits will always be set in
tandem, however, because the code was only looking for an exact
match, this detection broke now that `os.ModeCharDevice` was added.
This patch changes the code to be more defensive, and instead
check if the `os.ModeDevice` bit is set (either with, or without
the `os.ModeCharDevice` bit).
In addition, some information was added to the error-message if
no type was matched, to assist debugging in case additional types
are added in future.

The Swarmkit api specifies a target for configs called called "Runtime"
which indicates that the config is not mounted into the container but
has some other use. This commit updates the Docker api to reflect this.

Here's what happens:
1. One runs `make binary` once
2. Days go by...
3. One makes changes to dockerd sources
4. One runs `make test-integration` to test the changes
5. One spends a long time figuring out why on Earth
those changes in step 3 are ignored by step 4.
6. One writes this patch
7. ...
8. PROFIT!!
OK, so `make test-integration` builds a dockerd binary
in bundles/dynbinary-daemon/, when starts a daemon instance
for testing. The problem is, the script that starts the
daemon sets PATH to try `bundles/binary-daemon/` first,
and `bundles/dynbinary-daemon/` second.

containerd has two objects with regard to containers.
There is a "container" object which is metadata and a "task" which is
manging the actual runtime state.
When docker starts a container, it creartes both the container metadata
and the task at the same time. So when a container exits, docker deletes
both of these objects as well.
This ensures that if, on start, when we go to create the container metadata object
in containerd, if there is an error due to a name conflict that we go
ahead and clean that up and try again.
