Both of these were deprecated in 55f675811a,
but the format of the GoDoc comments didn't follow the correct format, which
caused them not being picked up by tools as "deprecated".

I think this was there for historic reasons (may have been goimports expected
this, and we used to have a linter that wanted it), but it's not needed, so
let's remove it (to make my IDE less complaining about unneeded aliases).

This removes some of the checks that were added in 0cba7740d4,
but should no longer be needed.
- `image/store.Delete()`: no need to validate image platform to delete it.
- `image/tarexporter/takeLayerReference()`: use `image.OperatingSystem()` and
fail early to prevent constructing the `ChainID()`.

The LCOW implementation in dockerd has been deprecated in favor of re-implementation
in containerd (in progress). Microsoft started removing the LCOW V1 code from the
build dependencies we use in Microsoft/opengcs (soon to be part of Microsoft/hcshhim),
which means that we need to start removing this code.
This first step removes the lcow graphdriver, the LCOW initialization code, and
some LCOW-related utilities.

"docker load" validates parent links by comparing image histories, and the
History struct has a time.Time member "Created". Time.UnmarshalJSON can read
RFC3339 timestamps with offset "+00:00", but t.MarshalJSON writes them with
offset "Z". Equivalent times in these two formats are not equal when compared
with the == operator.
This causes checkValidParent to incorrectly return false when the parent image
history contains times using offset "+00:00". In that case the history copied
to the child image will have been converted into "Z" form when marshaled out.
This patch adds an "Equal" method to History, which compares "Created" times
with t.Equal. This is used instead of reflect.DeepEqual in checkValidParent.

This commit adds the image variant to the image.(Image) type and
updates related functionality. Images built from another will
inherit the OS, architecture and variant.
Note that if a base image does not specify an architecture, the
local machine's architecture is used for inherited images. On the
other hand, the variant is set equal to the parent image's variant,
even when the parent image's variant is unset.
The legacy builder is also updated to allow the user to specify
a '--platform' argument on the command line when creating an image
FROM scratch. A complete platform specification, including variant,
is supported. The built image will include the variant, as will any
derived images.

This commit is a pre-requisite to moving moby/moby on Windows to using
Containerd for its runtime.
The reason for this is that the interface between moby and containerd
for the runtime is an OCI spec which must be unambigious.
It is the responsibility of the runtime (runhcs in the case of
containerd on Windows) to ensure that arguments are escaped prior
to calling into HCS and onwards to the Win32 CreateProcess call.
Previously, the builder was always escaping arguments which has
led to several bugs in moby. Because the local runtime in
libcontainerd had context of whether or not arguments were escaped,
it was possible to hack around in daemon/oci_windows.go with
knowledge of the context of the call (from builder or not).
With a remote runtime, this is not possible as there's rightly
no context of the caller passed across in the OCI spec. Put another
way, as I put above, the OCI spec must be unambigious.
The other previous limitation (which leads to various subtle bugs)
is that moby is coded entirely from a Linux-centric point of view.
Unfortunately, Windows != Linux. Windows CreateProcess uses a
command line, not an array of arguments. And it has very specific
rules about how to escape a command line. Some interesting reading
links about this are:
https://blogs.msdn.microsoft.com/twistylittlepassagesallalike/2011/04/23/everyone-quotes-command-line-arguments-the-wrong-way/https://stackoverflow.com/questions/31838469/how-do-i-convert-argv-to-lpcommandline-parameter-of-createprocesshttps://docs.microsoft.com/en-us/cpp/cpp/parsing-cpp-command-line-arguments?view=vs-2017
For this reason, the OCI spec has recently been updated to cater
for more natural syntax by including a CommandLine option in
Process.
What does this commit do?
Primary objective is to ensure that the built OCI spec is unambigious.
It changes the builder so that `ArgsEscaped` as commited in a
layer is only controlled by the use of CMD or ENTRYPOINT.
Subsequently, when calling in to create a container from the builder,
if follows a different path to both `docker run` and `docker create`
using the added `ContainerCreateIgnoreImagesArgsEscaped`. This allows
a RUN from the builder to control how to escape in the OCI spec.
It changes the builder so that when shell form is used for RUN,
CMD or ENTRYPOINT, it builds (for WCOW) a more natural command line
using the original as put by the user in the dockerfile, not
the parsed version as a set of args which loses fidelity.
This command line is put into args[0] and `ArgsEscaped` is set
to true for CMD or ENTRYPOINT. A RUN statement does not commit
`ArgsEscaped` to the commited layer regardless or whether shell
or exec form were used.

Addresses https://github.com/moby/moby/pull/35089#issuecomment-367802698.
This change enables the daemon to automatically select an image under LCOW
that can be used if the API doesn't specify an explicit platform.
For example:
FROM supertest2014/nyan
ADD Dockerfile /
And docker build . will download the linux image (not a multi-manifest image)
And similarly docker pull ubuntu will match linux/amd64
Embedded new lines aren't interpreted correctly in markdown renderers (they are treated as preformatted text instead). I removed the embedded newlines in the docker image spec.

Currently we hardcode the architecture to the `runtime.GOARCH` when
building a docker image, this will result in a confusing info if the
arch in the base image is different from the one on the host.
This PR takes use of the arch data from the base image during the build
process, thus we can get consistent arch info between the base image
and the finally built image.

In info, we only need the number of images, but `CountImages` was
getting the whole map of images and then grabbing the length from that.
This causes a lot of unnecessary CPU usage and memory allocations, which
increases with O(n) on the number of images.
