Go 1.13 and up enforce import paths to be versioned if a project
contains a go.mod and has released v2 or up.
The current v2.x branches (and releases) do not yet have a go.mod,
and therefore are still allowed to be imported with a non-versioned
import path (go modules add a `+incompatible` annotation in that case).
However, now that this project has a `go.mod` file, incompatible
import paths will not be accepted by go modules, and attempting
to use code from this repository will fail.
This patch uses `v3` for the import-paths (not `v2`), because changing
import paths itself is a breaking change, which means that the
next release should increment the "major" version to comply with
SemVer (as go modules dictate).

Partially reverts change adding support for X-Forwarded-Port.
Changes the logic to prefer the standard Forwarded header over
X-Forwarded headers. Prefer forwarded "host" over "for" since
"for" represents the client and not the client's request.

Since there's no default case, if there's not a tag or digest you get
back a confusing error from the router about it not matching the
expected pattern.
Also redoing the tests for URLs a bit so that they can handle checking
for failures.

Prefer non-standard headers like X-Forwarded-Proto, X-Forwarded-Host and
X-Forwarded-Port over the standard Forwarded header to maintain
backwards compatibility.
If a port is not specified neither in Host nor in forwarded headers but
it is specified just with X-Forwarded-Port, use its value in base urls
for redirects.
Forwarded header is defined in rfc7239.
X-Forwarded-Port is a non-standard header. Here's a description copied
from "HTTP Headers and Elastic Load Balancing" of AWS ELB docs:
> The X-Forwarded-Port request header helps you identify the port that
> an HTTP or HTTPS load balancer uses to connect to the client.

Most places in the registry were using string types to refer to
repository names. This changes them to use reference.Named, so the type
system can enforce validation of the naming rules.

This change adds a basic catalog endpoint to the API, which returns a list,
or partial list, of all of the repositories contained in the registry. Calls
to this endpoint are somewhat expensive, as every call requires walking a
large part of the registry.
Instead, to maintain a list of repositories, you would first call the catalog
endpoint to get an initial list, and then use the events API to maintain
any future repositories.

According to the Apache mod_proxy docs, X-Forwarded-Host can be a
comma-separated list of hosts, to which each proxy appends the requested
host. We want to grab only the first from this comma-separated list
to get the original requested Host when building URLs.

Manifests are now fetched by a field called "reference", which may be a tag or
a digest. When using digests to reference a manifest, the data is immutable.
The routes and specification have been updated to allow this.
There are a few caveats to this approach:
1. It may be problematic to rely on data format to differentiate between a tag
and a digest. Currently, they are disjoint but there may modifications on
either side that break this guarantee.
2. The caching characteristics of returned content are very different for
digest versus tag-based references. Digest urls can be cached forever while tag
urls cannot.
Both of these are minimal caveats that we can live with in the future.
