The "shortid" syntax was added in d26a3b37a6,
and allowed for matching an image on its ID prefix (this is before images were
content-addressable). With the introduction of content-addressable references,
this syntax became problematic, and Docker deprecated this syntax in 2016
(Docker v1.13.0) through commit; 5fc71599a0
> The `repository:shortid` syntax for referencing images is very little used,
> collides with tag references, and can be confused with digest references.
Support for this syntax was removed in 2017 (Docker 17.12) through commit:
a942c92dd7
containerd uses a fork of the reference package with this syntax removed, and
does not support this syntax:
901bcb2231
This patch removes the deprecated syntax, the ParseAnyReferenceWithSet function,
and the ShortIdentifierRegexp regex.
As there are no external consumers for this function, nor the regexp, I'm
skipping a deprecation cycle for this;
- https://grep.app/search?q=.ShortIdentifierRegexp
- https://grep.app/search?q=.ParseAnyReferenceWithSet%28

gofumpt (https://github.com/mvdan/gofumpt) provides a supserset of `gofmt` / `go fmt`,
and addresses various formatting issues that linters may be checking for.
We can consider enabling the `gofumpt` linter to verify the formatting in CI, although
not every developer may have it installed, so for now this runs it once to get formatting
in shape.

Instead of first collecting all keys and then batch deleting them,
we will do the incremental delete _online_ per max allowed batch.
Doing this prevents frequent allocations for large S3 keyspaces
and OOM-kills that might happen as a result of those.
This commit introduces storagedriver.Errors type that allows to return
multierrors as a single error from any storage driver implementation.

1, return the right upload offset for client when asks.
2, do not call ResumeBlobUpload on getting status.
3, return 416 rather than 404 on failed to patch chunk blob.
4, add the missing upload close

Instead of letting the cache grow without bound, use a LRU to impose a
size limit.
The limit is configurable through a new `blobdescriptorsize` config key.

These tests don't validate if options are valid for the storage-driver,
nor do they test if the storage-driver itself is valid. However, the tests
were using actual values (such as s3) and options (such as "region") which
may lead to the conclusion that it's also testing validity of those values.
This patch replaces the test-values with non-existing driver-names and
options to make it more clear these are fake values.

This simple change mainly affects the distribution client. By respecting
the context the caller passes in, timeouts and cancellations will work
as expected. Also, transports which rely on the context (such as tracing
transports that retrieve a span from the context) will work properly.

The example shows a `GET` request to `/callback`, but it looks like it's
intending to show the `POST` request made by the registry to a
notificaitons endpoint. Unless I'm missing something, no `GET` request
should be involved.

(*App).context, called in the HTTP handler on each request, creates a
URLBuilder, which involves calling Router(). This shows up in profiles a
hot spot because it involves compiling the regexps which define all the
routes. For efficiency, cache the router and return the same object each
time.
It appears to be safe to reuse the router because GetRoute is the only
method ever called on the returned router object.

As the project has transitioned from Docker to CNCF, clean up the
contributing.md to reflect that:
- CNCF slack
- CNCF maintainers
- Use with other container tools

Current registry reference use a subset of dns and IPv4 addresses to
represent a registry domain.
Since registries are mostly compatible with rfc3986, that defines the
URI generic syntax, this adds support for IPv6 enclosed in squared
brackets based on the mentioned rfc.
The regexp is only expanded to match on IPv6 addreses enclosed between
square brackets, considering only regular IPv6 addresses represented
as compressed or uncompressed, excluding special IPv6 address
representations.
