The re-coalesces the daemon stores which were split as part of the
original LCOW implementation.
This is part of the work discussed in https://github.com/moby/moby/issues/34617,
in particular see the document linked to in that issue.
Libcontainer no longer provides placeholders for
unsupported platforms, which cause the Windows
builds to fail.
This patch moves features that are not supported
to platform-specific files.

This PR contains a fix for moby/moby#30321. There was a moby/moby#31142
PR intending to fix the issue by adding a delay between disabling the
service in the cluster and the shutdown of the tasks. However
disabling the service was not deleting the service info in the cluster.
Added a fix to delete service info from cluster and verified using siege
to ensure there is zero downtime on rolling update of a service.In order
to support it and ensure consitency of enabling and disable service knob
from the daemon, we need to ensure we disable service when we release
the network from the container. This helps in making the enable and
disable service less racy. The corresponding part of libnetwork fix is
part of docker/libnetwork#1824

A linter (vet) found the following bug in the code:
> daemon/metrics.go:124::error: range variable p captured by func literal (vet)
Here a variable p is used in an async fashion by goroutine, and most
probably by the time of use it is set to the last element of a range.
For example, the following code
```go
for _, c := range []string{"here ", "we ", "go"} {
go func() {
fmt.Print(c)
}()
}
```
will print `gogogo` rather than `here we go` as one would expect.

1. Add = between the option and the argument, otherwise the argument
appears to be passed on to the linters directly, as in:
> DEBUG: [golint.8]: executing /home/kir/go/bin/golint
> -min_confidence 0.800000 ./10m ./api ./api/errdefs <...>
2. Fix setting the default for GOMETALINTER_OPTS -- the default
was -deadline (rather than --deadline).

It's a common scenario for admins and/or monitoring applications to
mount in the daemon root dir into a container. When doing so all mounts
get coppied into the container, often with private references.
This can prevent removal of a container due to the various mounts that
must be configured before a container is started (for example, for
shared /dev/shm, or secrets) being leaked into another namespace,
usually with private references.
This is particularly problematic on older kernels (e.g. RHEL < 7.4)
where a mount may be active in another namespace and attempting to
remove a mountpoint which is active in another namespace fails.
This change moves all container resource mounts into a common directory
so that the directory can be made unbindable.
What this does is prevents sub-mounts of this new directory from leaking
into other namespaces when mounted with `rbind`... which is how all
binds are handled for containers.

The `POST /volumes/create` expects a request body to be provided.
If no body was provided, a 500 status was returned. A 500 status
is incorrect, because the request is invalid (it's not a server
error).

The Golang built-in gzip library is serialized, and fairly slow
at decompressing. It also only decompresses on demand, versus
pipelining decompression.
This change switches to using the pigz external command
for gzip decompression, as opposed to using the built-in
golang one. This code is not vendored, but will be used
if it autodetected as part of the OS.
This also switches to using context, versus a manually
managed channel to manage cancellations, and synchronization.
There is a little bit of weirdness around manually having
to cancel in the error cases.
