The github.com/containerd/containerd/log package was moved to a separate
module, which will also be used by upcoming (patch) releases of containerd.
This patch moves our own uses of the package to use the new module.

Implement a function that returns an error to replace existing uses of
the IsOSSupported utility, where callers had to produce the error after
checking.
The IsOSSupported function was used in combination with images, so implementing
a utility in "image" to prevent having to import pkg/system (which contains many
unrelated functions)

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.

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.

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.

- 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.

Define consts for the Actions we use for events, instead of "ad-hoc" strings.
Having these consts makes it easier to find where specific events are triggered,
makes the events less error-prone, and allows documenting each Action (if needed).

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.

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).

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.

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.

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

The image store's used are an interface, so there's no guarantee
that implementations don't wrap the errors. Make sure to catch
such cases by using errors.Is.

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 :)

Having this function hides what it's doing, which is just to type-cast
to an image.ID (which is a digest). Using a cast is more transparent,
so deprecating this function in favor of a regular typecast.

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".
This patch updates uses in the codebase to use the alternatives.

different aliases for the same package.

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()`.
