This workaround for golang/go#15286 was added for Nano server TP5 in
fa82c0aa10cfac8c6d5e2446876dc79b2b0c1bf9, and should no longer be
needed
Due to a security fix in Go 1.9.4/1.8.7, loading the .dll is no longer
allowed, and produces an error:

Daemon flags that can be specified multiple times use
singlar names for flags, but plural names for the configuration
file.
To make the daemon configuration know how to correlate
the flag with the corresponding configuration option,
`opt.NewNamedListOptsRef()` should be used instead of
`opt.NewListOptsRef()`.
Commit 6702ac590e6148cb3f606388dde93a011cb14931 attempted
to fix the daemon not corresponding the flag with the configuration
file option, but did so by changing the name of the flag
to plural.
This patch reverts that change, and uses `opt.NewNamedListOptsRef()`
instead.

Interacting with v1 registries was deprecated in Docker 1.8.3, disabled by default
in Docker 17.06, and scheduled for removal in Docker 17.12.
This patch disallows enabling V1 registry through the `--disable-legacy-registry`
option, and the `"disable-legacy-registry": false` option in the daemon configuration
file. The actual V1 registry code is still in place, and will be removed separately.
With this patch applied:
$ dockerd --disable-legacy-registry=false
ERROR: The '--disable-legacy-registry' flag has been removed. Interacting with legacy (v1) registries is no longer supported
Or, when setting through the `daemon.json` configuration file

This PR has the API changes described in https://github.com/moby/moby/issues/34617.
Specifically, it adds an HTTP header "X-Requested-Platform" which is a JSON-encoded
OCI Image-spec `Platform` structure.
In addition, it renames (almost all) uses of a string variable platform (and associated)
methods/functions to os. This makes it much clearer to disambiguate with the swarm
"platform" which is really os/arch. This is a stepping stone to getting the daemon towards
fully multi-platform/arch-aware, and makes it clear when "operating system" is being
referred to rather than "platform" which is misleadingly used - sometimes in the swarm
meaning, but more often as just the operating system.

Since the commit d88fe447df0e8 ("Add support for sharing /dev/shm/ and
/dev/mqueue between containers") container's /dev/shm is mounted on the
host first, then bind-mounted inside the container. This is done that
way in order to be able to share this container's IPC namespace
(and the /dev/shm mount point) with another container.
Unfortunately, this functionality breaks container checkpoint/restore
(even if IPC is not shared). Since /dev/shm is an external mount, its
contents is not saved by `criu checkpoint`, and so upon restore any
application that tries to access data under /dev/shm is severily
disappointed (which usually results in a fatal crash).
This commit solves the issue by introducing new IPC modes for containers
(in addition to 'host' and 'container:ID'). The new modes are:
- 'shareable': enables sharing this container's IPC with others
(this used to be the implicit default);
- 'private': disables sharing this container's IPC.
In 'private' mode, container's /dev/shm is truly mounted inside the
container, without any bind-mounting from the host, which solves the
issue.
While at it, let's also implement 'none' mode. The motivation, as
eloquently put by Justin Cormack, is:
> I wondered a while back about having a none shm mode, as currently it is
> not possible to have a totally unwriteable container as there is always
> a /dev/shm writeable mount. It is a bit of a niche case (and clearly
> should never be allowed to be daemon default) but it would be trivial to
> add now so maybe we should...
...so here's yet yet another mode:
- 'none': no /dev/shm mount inside the container (though it still
has its own private IPC namespace).
Now, to ultimately solve the abovementioned checkpoint/restore issue, we'd
need to make 'private' the default mode, but unfortunately it breaks the
backward compatibility. So, let's make the default container IPC mode
per-daemon configurable (with the built-in default set to 'shareable'
for now). The default can be changed either via a daemon CLI option
(--default-shm-mode) or a daemon.json configuration file parameter
of the same name.
Note one can only set either 'shareable' or 'private' IPC modes as a
daemon default (i.e. in this context 'host', 'container', or 'none'
do not make much sense).
Some other changes this patch introduces are:
1. A mount for /dev/shm is added to default OCI Linux spec.
2. IpcMode.Valid() is simplified to remove duplicated code that parsed
'container:ID' form. Note the old version used to check that ID does
not contain a semicolon -- this is no longer the case (tests are
modified accordingly). The motivation is we should either do a
proper check for container ID validity, or don't check it at all
(since it is checked in other places anyway). I chose the latter.
3. IpcMode.Container() is modified to not return container ID if the
mode value does not start with "container:", unifying the check to
be the same as in IpcMode.IsContainer().
3. IPC mode unit tests (runconfig/hostconfig_test.go) are modified
to add checks for newly added values.
