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.

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.

Allows having other parsers which are capable of unambiguously keeping domain and path separated in a Reference type.

This allows hostnames to contain uppercase characters, matching behavior
in Docker versions before 1.10. It does not attempt to canonicalize
hostnames into a lowercase format before parsing, since this could lead
to corner cases (for example, making Hostname.Domain.Com/ref ambiguous
on a daemon which contains references for both hostname.domain.com/ref
and Hostname.Domain.Com/ref).
Fixes: #1433

To resolve some inconsistencies between the grammar and the regular
expressions, the grammar has been slightly refactored to match the intent. The
regular expressions have been redefined with the same structure to make it
easier to verify the grammar is correct.

In order to support valid hostnames as name components, supporting repeated dash was added.
Additionally double underscore is now allowed as a separator to loosen the restriction for previously supported names.
