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.

The test was depending on the client constructing an error based on the
http-status code, and the client not reading the response body if the
response was not a JSON response.
This fix;
- adds the correct content-type headers in the response
- includes error-messages in the response
- adds additional tests to cover both the plain (non-JSON) and JSON
error responses, as well as an empty response.

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 used when the code supported both "v1" and "v2" registries.
We no longer support v1 registries, and the only v1 endpoint that's still
used is for the legacy "search" endpoint, which does not use the APIEndpoint
type.
As no code is using this field, and the value will always be set to "v2",
we can deprecated the Version field.
I'm keeping this field for 1 release, to give notice to any potential
external consumer, after which we can delete it.

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).

When we added this deprecation warning, some registries had not yet
moved away from the deprecated specification, so we made the warning
conditional for pulling from Docker Hub.
That condition was added in 647dfe99a5,
which is over 4 Years ago, which should be time enough for images
and registries to have moved to current specifications.

- Use the same warning for both "v1 in manifest-index" and bare "v1" images.
- Update URL to use a "/go/" redirect, which allows the docs team to more
easily redirect the URL to relevant docs (if things move).

The signatures of functions in containerd's errdefs packages are very
similar to those in our own, and it's easy to accidentally use the wrong
package.
This patch uses a consistent alias for all occurrences of this import.

maxDownloadAttempts maps to the daemon configuration flag
--max-download-attempts int
Set the max download attempts for each pull (default 5)
and the daemon configuration machinery interprets a value of 0 as "apply
the default value" and not a valid user value (config validation/
normalization bugs notwithstanding). The intention is clearly that this
configuration value should be an upper limit on the number of times the
daemon should try to download a particular layer before giving up. So it
is surprising to have the configuration value interpreted as a _retry_
limit. The daemon will make up to N+1 attempts to download a layer! This
also means users cannot disable retries even if they wanted to.
Fix the fencepost bug so that max attempts really means max attempts,
not max retries. And fix the fencepost bug with the retry-backoff delay
so that the first backoff is 5s, not 10s.

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.

This addresses a regression introduced in 407e3a4552,
which turned out to be "too strict", as there's old images that use, for example;
docker pull python:3.5.1-alpine
3.5.1-alpine: Pulling from library/python
unsupported media type application/octet-stream
Before 407e3a4552, such mediatypes were accepted;
docker pull python:3.5.1-alpine
3.5.1-alpine: Pulling from library/python

Status: Downloaded newer image for python:3.5.1-alpine

This patch copies the additional media-types, using the list of types that
were added in a215e15cb1, which fixed a
similar issue.

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".

Currently an attempt to pull a reference which resolves to an OCI
artifact (Helm chart for example), results in a bit unrelated error
message `invalid rootfs in image configuration`.
This provides a more meaningful error in case a user attempts to
download a media type which isn't image related.

This fallback is used when we filter the manifest list by the user-provided platform and find no matches such that we match the previous Docker behavior (before it supported variant matching). This has been deprecated long enough that I think it's time we finally stop supporting this weird fallback, especially since it makes for buggy behavior like `docker pull --platform linux/arm/v5 alpine:3.16` leading to a `linux/arm/v6` image being pulled (I specified a variant, every manifest list entry specifies a variant, so clearly the only behavior I as a user could reasonably expect is an error that `linux/arm/v5` is not supported, but instead I get an explicitly incompatible image despite doing everything I as a user can to prevent that situation).

This debug message already includes a full platform string, so this ends up being something like `linux/arm/v7/amd64` in the end result.

This is accomplished by storing the distribution source in the content
labels. If the distribution source is not found then we check to the
registry to see if the digest exists in the repo, if it does exist then
the puller will use it.

- Manifest list is allowed to contain manifest lists
- Unknown mediatype inside manifest list is skipped instead of causing an error
- Platform in descriptor is optional

These were only exported to facilitate ImageService.GetRepository() (used for
the `GET /distribution/{name:.*}/json` endpoint.
Moving the core functionality of that to the distribution package makes it
more consistent with (e.g.) "pull" operations, and allows us to keep more things
internal.

It's only used internally, so we can refer to the implementation itself. Given
that RegistryService.LookupPushEndpoints now only returns V2 endpoints, we
no longer need to check if an endpoint is possibly V1.
Also rename some types that had "v2" in their name, now that we only support v2.
