when it is passed with bad arguments and no arguments. This patch would divide the total number of commands into five sets and runs them in parallel.

Why? Because the `mount` here will sometimes fail when run in
`debian:jessie`, which is what the environrment hosting the test suite
is running if run from the `Makefile`.
Also, why the heck not containerize it, all the things.

Docker 1.5 and older is no longer supported by Docker Hub,
so there's not much need to document the API for those
versions.
Documentation is still available on GitHub, and through
the older versions of the documentation for those
that really need it.

This fix tries to fix issues mentioned in #22100 for incorrect
description of remote API's container creation params.
Several issues have been fixed:
1. CPU and memory related params (e.g., `MemorySwap`, `CpuShares`, etc.)
were incorrectly placed under the top level instead of under the HostConfig.
(v1.18-v1.24)
2. The param `Cpuset` has been deprecated but was never removed.
(v1.18-v1.24)
3. The param `PidsLimit` was not added even though the description
has been added.
(v1.23-v1.24)
This fix fixes#22100

pidfile.New() was opening a file in /proc to determine if the owning
process still exists. Use syscall.OpenProcess() on Windows instead.
Other OSes may also need to be updated here.

People have reported following issue with overlay
$ docker run -ti --name=foo -v /dev/:/dev fedora bash
$ docker cp foo:/bin/bash /tmp
$ exit container
Upon container exit, /dev/pts gets unmounted too. This happens because
docker cp volume mounts get propagated to /run/docker/libcontainer/....
and when container exits, it must be tearing down mount point under
/run/docker/libcontainerd/... and as these are "shared" mounts it
propagates events to /dev/pts and it gets unmounted too.
One way to solve this problem is to make sure "docker cp" volume mounts
don't become visible under /run/docker/libcontainerd/..
Here are more details of what is actually happening.
Make overlay home directory (/var/lib/docker/overlay) private mount when
docker starts and unmount it when docker stops. Following is the reason
to do it.
In fedora and some other distributions / is "shared". That means when
docker creates a container and mounts it root in /var/lib/docker/overlay/...
that mount point is "shared".
Looks like after that containerd/runc bind mounts that rootfs into
/runc/docker/libcontainerd/container-id/rootfs. And this puts both source
and destination mounts points in shared group and they both are setup
to propagate mount events to each other.
Later when "docker cp" is run it sets up container volumes under
/var/lib/dokcer/overlay/container-id/... And all these mounts propagate
to /runc/docker/libcontainerd/... Now mountVolumes() makes these new
mount points private but by that time propagation already has happened
and private only takes affect when unmount happens.
So to stop this propagation of volumes by docker cp, make
/var/lib/docker/overlay a private mount point. That means when a container
rootfs is created, that mount point will be private too (it will inherit
property from parent). And that means when bind mount happens in /runc/
dir, overlay mount point will not propagate mounts to /runc/.
Other graphdrivers like devicemapper are already doing it and they don't
face this issue.

link feature in docker0 bridge by default provides short-id as a
container alias. With built-in SD feature, providing a container
short-id as a network alias will fill that gap.
