distribution: Error when pulling OCI artifacts
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.

distribution: un-export internal errors and error-utilities
un-exports errors that were only used internally:

- Remove ErrNoSupport as it was not emitted anywhere
- ImageConfigPullError -> imageConfigPullError
- TranslatePullError() -> translatePullError()

495d623ae5 Add fallback for pull by tag
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.

Include original error when translating distribution errors
Before:

    curl -v -X POST --unix-socket /var/run/docker.sock "http://localhost/images/create?fromImage=library/busybox:lsfkjsdflkjsdf"
    {"message":"manifest for busybox:lsfkjsdflkjsdf not found"}

    curl -v -X POST --unix-socket /var/run/docker.sock "http://localhost/images/create?fromImage=library/nosuchimage:latest"
    {"message":"pull access denied for nosuchimage, repository does not exist or may require 'docker login'"}

After:

    curl -v -X POST --unix-socket /var/run/docker.sock "http://localhost/images/create?fromImage=library/busybox:lsfkjsdflkjsdf"
    {"message":"manifest for busybox:lsfkjsdflkjsdf not found: manifest unknown: manifest unknown"}

    curl -v -X POST --unix-socket /var/run/docker.sock "http://localhost/images/create?fromImage=library/nosuchimage:latest"
    {"message":"pull access denied for nosuchimage, repository does not exist or may require 'docker login': denied: requested access to the resource is denied"}

87a12421a9 Add helpers to create errdef errors
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)
```

ebcb7d6b40 Remove string checking in API error handling
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.

Use distribution reference
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.

5e8af46fda Smarter push/pull TLS fallback
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"

8f26fe4f59 Push/pull errors improvement and cleanup
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.
