We make sure they're not hiding at the bottom or in the middle
which makes debugging an utter nightmare!

The specifics of how the authorization for a request is propagated
through the registry app are private implementation details. Hide those
details from outsiders so they can be changed as needed without fear of
breaking third-party code. Move the utilities for attaching a request's
authorization status to its context and retrieving it from the context
into the registry/handlers package as unexported symbols.

The details of how request-scoped information is propagated through the
registry server app should be left as private implementation details so
they can be changed without fear of breaking compatibility with
third-party code which imports the distribution module. The
AccessController interface unnecessarily bakes into the public API
details of how authorization grants are propagated through request
contexts. In practice the only values the in-tree authorizers attach to
the request contexts are the UserInfo and Resources for the request.
Change the AccessController interface to return the UserInfo and
Resources directly to allow us to change how request contexts are used
within the app without altering the AccessController interface contract.

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.

Back in the before time, the best practices surrounding usage of Context
weren't quite worked out. We defined our own type to make usage easier.
As this packaged was used elsewhere, it make it more and more
challenging to integrate with the forked `Context` type. Now that it is
available in the standard library, we can just use that one directly.
To make usage more consistent, we now use `dcontext` when referring to
the distribution context package.

Use whitelist of allowed repository classes to enforce.
By default all repository classes are allowed.
Add authorized resources to context after authorization.

This removes the erroneous http.Handler interface in favor a simple SetHeaders
method that only operattes on the response. Several unnecessary uses of pointer
types were also fixed up.

See: 3ea67df373/registry/handlers/app.go (L498)
Per the comment on line 498, this moves the logic of setting the http
status code into the serveJSON func, leaving the auth.Challenge.ServeHTTP()
func to just set the auth challenge header.
