image/spec: add missing "Shell" field (v1.2)
This field was added in b18ae8c9cc, which
was part of v1.12.0-rc1 and later, which used image spec v1.2.0.

This patch amends the v1.2 spec to include the missing field.

image/spec: add missing "ArgsEscaped" field (v1.1, v1.2)
This field was added in 9db5db1b94, which
was part of v1.10.0-rc1 and later, which used image spec v1.1.0.

It's worth noting that documentation for the v1.1.0 image spec was not
yet available until commit 4fa0eccd10,
which was included in v1.12.0-rc1 and up. The `ArgsEscaped` field was
also adopted by the OCI image spec since [v1.1.0-rc3][1], but considered
deprecated, and not recommended to be used.

This patch amends the v1.1 and v1.2 specifications to describe the field.

image/spec: add missing "OnBuild" field
This field was added in commit 9f994c9646,
which was merged before the image-spec v1.0.0 was released (which happened
in commit 79910625f0).

This patch backfills the specifications to describe the property.

image/spec: minor fixes and touch-ups in markdown files
- remove some trailing commas, which made the JSON invalid (some of these
  were fixed in the 1.2 spec, but not in older versions).
- synchronise some formatting / phrasing between versions, to make them
  easier to compare.
- remove non-breaking spaces (`NBSP`) in example outputs, and replace
  them with regular spaces.

c8d/builder: Don't drop fields from created image
Previous image created a new partially filled image.
This caused child images to lose their parent's layers.

Instead of creating a new object and trying to replace its fields, just
clone the original passed image and change its ID to the manifest
digest.

2a6ff3c24f Use OCI "History" type instead of inventing our own copy
The most notable change here is that the OCI's type uses a pointer for `Created`, which we probably should've been too, so most of these changes are accounting for that (and embedding our `Equal` implementation in the one single place it was used).

1e55ace875 Add oci index and layout files to exported tars
This makes the output of `docker save` fully OCI compliant.

When using the containerd image store, this code is not used. That
exporter will just use containerd's export method and should give us the
output we want for multi-arch images.

ddd67b2535 Make image save more like the OCI layout for blobs
This moves the blobs around so they follow the OCI spec.
Note that because docker reads paths from the manifest.json inside the
tar this is not a breaking change.

This does, however, remove the old layer "VERSION" file which had a big
"why is this even here" in the code comments. I suspect it does not
matter at all even for really old versions of Docker. In any case it is
a useless file for any even relatively modern version of Docker.

1616a09b61 add support for image inspect with containerd-integration
This is a squashed version of various PRs (or related code-changes)
to implement image inspect with the containerd-integration;

- add support for image inspect
- introduce GetImageOpts to manage image inspect data in backend
- GetImage to return image tags with details
- list images matching digest to discover all tags
- Add ExposedPorts and Volumes to the image returned
- Refactor resolving/getting images
- Return the image ID on inspect
- consider digest and ignore tag when both are set
- docker run --platform

image: store.restore(): use more structured logs
This code below is run when restoring all images (which can be "many"),
constructing the "logrus.WithFields" is deliberately not "DRY", as the
logger is only used for error-cases, and we don't want to do allocations
if we don't need it. A "f" type-alias was added to make it ever so slightly
more DRY, but that's just for convenience :)

image: deprecate IDFromDigest()

Remove LCOW code (step 1)
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.

Fix spurious error from "docker load"
"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.

c21a3cf432 Add variant to image.Image and legacy builder
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.
