Support for PidsLimit was added to SwarmKit in docker/swarmkit/pull/2415,
but never exposed through the Docker remove API.
This patch exposes the feature in the repote API.

Adding separate documents for older API versions, so that these don't have to
be collected from each tag/release branch. For each version of the API, I picked
the highest release that uses the API (to make sure to include possible fixes
in the swagger);

Metrics collectors generally don't need the daemon to prime the stats
with something to compare since they already have something to compare
with.
Before this change, the API does 2 collection cycles (which takes
roughly 2s) in order to provide comparison for CPU usage over 1s. This
was primarily added so that `docker stats --no-stream` had something to
compare against.
Really the CLI should have just made a 2nd call and done the comparison
itself rather than forcing it on all API consumers.
That ship has long sailed, though.
With this change, clients can set an option to just pull a single stat,
which is *at least* a full second faster:
Old:
```
time curl --unix-socket
/go/src/github.com/docker/docker/bundles/test-integration-shell/docker.sock
http://./containers/test/stats?stream=false\&one-shot=false > /dev/null
2>&1

2>&1
real0m1.173s
user0m0.010s
sys0m0.006s
```
New:
```
time curl --unix-socket
/go/src/github.com/docker/docker/bundles/test-integration-shell/docker.sock
http://./containers/test/stats?stream=false\&one-shot=true > /dev/null
2>&1

2>&1

This fixes issues with downstreams ability to use the stats API to
collect metrics.

This adds a new `fluentd-request-ack` logging option for the Fluentd
logging driver. If enabled, the server will respond with an acknowledgement.
This option improves the reliability of the message transmission. This
change is not versioned, and affects all API versions.

This query-parameter was deprecated in docker 1.13 in commit
820b809e70, and scheduled for
removal in docker 17.12, so we should remove it for the next
API version.

The `/session` endpoint left experimental in API V1.39 through

Unlike Linux which uses a temp dir as GOPATH, Windows
uses c:\go. Among other things, this blocks go get.
Moving GOPATH to c:\gopath and updating references in
comments and documentation.
Currently the change is being scoped narrowly. In the
future GOPATH value could be passed as a parameter to
the ps1 scripts.

This adds both a daemon-wide flag and a container creation property:
- Set the `CgroupnsMode: "host|private"` HostConfig property at
container creation time to control what cgroup namespace the container
is created in
- Set the `--default-cgroupns-mode=host|private` daemon flag to control
what cgroup namespace containers are created in by default
- Set the default if the daemon flag is unset to "host", for backward
compatibility
- Default to CgroupnsMode: "host" for client versions < 1.40

lxc-user-nic can eliminate slirp overhead but needs /etc/lxc/lxc-usernet to be configured for the current user.
To use lxc-user-nic, $DOCKERD_ROOTLESS_ROOTLESSKIT_NET=lxc-user-nic also needs to be set.

The `--rootless` flag had a couple of issues:
* #38702: euid=0, $USER="root" but no access to cgroup ("rootful" Docker in rootless Docker)
* #39009: euid=0 but $USER="docker" (rootful boot2docker)
To fix#38702, XDG dirs are ignored as in rootful Docker, unless the
dockerd is directly running under RootlessKit namespaces.
RootlessKit detection is implemented by checking whether `$ROOTLESSKIT_STATE_DIR` is set.
To fix#39009, the non-robust `$USER` check is now completely removed.
The entire logic can be illustrated as follows:
```
withRootlessKit := getenv("ROOTLESSKIT_STATE_DIR")
rootlessMode := withRootlessKit || cliFlag("--rootless")
honorXDG := withRootlessKit
useRootlessKitDockerProxy := withRootlessKit
removeCgroupSpec := rootlessMode
adjustOOMScoreAdj := rootlessMode
```

Now `docker run -p` ports can be exposed to the host namespace automatically when `dockerd-rootless.sh` is launched with
`--userland-proxy --userland-proxy-path $(which rootlesskit-docker-proxy)`.
This is akin to how Docker for Mac/Win works with `--userland-proxy-path=/path/to/vpnkit-expose-port`.
The port number on the host namespace needs to be set to >= 1024.
SCTP ports are currently unsupported.
