This patch disables pulling legacy (schema1 and schema 2, version 1) images by
default.
A `DOCKER_ENABLE_DEPRECATED_PULL_SCHEMA_1_IMAGE` environment-variable is
introduced to allow re-enabling this feature, aligning with the environment
variable used in containerd 2.0 (`CONTAINERD_ENABLE_DEPRECATED_PULL_SCHEMA_1_IMAGE`).
With this patch, attempts to pull a legacy image produces an error:
With graphdrivers:
docker pull docker:1.0
1.0: Pulling from library/docker
[DEPRECATION NOTICE] Docker Image Format v1, and Docker Image manifest version 2, schema 1 support will be removed in an upcoming release. Suggest the author of docker.io/library/docker:1.0 to upgrade the image to the OCI Format, or Docker Image manifest v2, schema 2. More information at https://docs.docker.com/go/deprecated-image-specs/
With the containerd image store enabled, output is slightly different
as it returns the error before printing the `1.0: pulling ...`:
docker pull docker:1.0
Error response from daemon: [DEPRECATION NOTICE] Docker Image Format v1 and Docker Image manifest version 2, schema 1 support is disabled by default and will be removed in an upcoming release.

Using the "distribution" endpoint to resolve the digest for an image also
produces an error:

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.

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.

Some registries seem to be non-conformant and return a not found error
when pulling by digest (which docker now does all the time).
To work around this, fallback when all of the following are true:
1. Image reference is a tag
2. Tag->digest resolution succeeds
3. Fetch by resolved digest fails with a "not found" error.
This is intentionally not caching the manifests to reduce complexity for
this edge case.

Instead of having to create a bunch of custom error types that are doing
nothing but wrapping another error in sub-packages, use a common helper
to create errors of the requested type.
e.g. instead of re-implementing this over and over:
```go
type notFoundError struct {
cause error
}
func(e notFoundError) Error() string {
return e.cause.Error()
}
func(e notFoundError) NotFound() {}
func(e notFoundError) Cause() error {
return e.cause
}
```
Packages can instead just do:
```
errdefs.NotFound(err)
```

Use strongly typed errors to set HTTP status codes.
Error interfaces are defined in the api/errors package and errors
returned from controllers are checked against these interfaces.
Errors can be wraeped in a pkg/errors.Causer, as long as somewhere in the
line of causes one of the interfaces is implemented. The special error
interfaces take precedence over Causer, meaning if both Causer and one
of the new error interfaces are implemented, the Causer is not
traversed.

Remove forked reference package. Use normalized named values
everywhere and familiar functions to convert back to familiar
strings for UX and storage compatibility.
Enforce that the source repository in the distribution metadata
is always a normalized string, ignore invalid values which are not.
Update distribution tests to use normalized values.

With the --insecure-registry daemon option (or talking to a registry on
a local IP), the daemon will first try TLS, and then try plaintext if
something goes wrong with the push or pull. It doesn't make sense to try
plaintext if a HTTP request went through while using TLS. This commit
changes the logic to keep track of host/port combinations where a TLS
attempt managed to do at least one HTTP request (whether the response
code indicated success or not). If the host/port responded to a HTTP
using TLS, we won't try to make plaintext HTTP requests to it.
This will result in better error messages, which sometimes ended up
showing the result of the plaintext attempt, like this:
Error response from daemon: Get
http://myregistrydomain.com:5000/v2/: malformed HTTP response
"\x15\x03\x01\x00\x02\x02"

Several improvements to error handling:
- Introduce ImageConfigPullError type, wrapping errors related to
downloading the image configuration blob in schema2. This allows for a
more descriptive error message to be seen by the end user.
- Change some logrus.Debugf calls that display errors to logrus.Errorf.
Add log lines in the push/pull fallback cases to make sure the errors
leading to the fallback are shown.
- Move error-related types and functions which are only used by the
distribution package out of the registry package.
