The registry package contained code to automatically set the CertsDir() path,
based on wether or not the daemon was running in rootlessmode. In doing so,
it made use of the `pkg/rootless.RunningWithRootlessKit()` utility.
A recent change in de6732a403 added additional
functionality in the `pkg/rootless` package, introducing a dependency on
`github.com/rootless-containers/rootlesskit`. Unfortunately, the extra
dependency also made its way into the docker cli, which also uses the
registry package.
This patch introduces a new `SetCertsDir()` function, which allows
the default certs-directory to be overridden, and updates the daemon
to configure this location during startup.

Move the default to the service itself, and produce the correct status code
if an invalid limit was specified. The default is currently set both on the
cli and on the daemon side, and it should be only set on one of them.
There is a slight change in behavior; previously, searching with `--limit=0`
would produce an error, but with this change, it's considered the equivalent
of "no limit set" (and using the default).
We could keep the old behavior by passing a pointer (`nil` means "not set"),
but I left that for a follow-up exercise (we may want to pass an actual
config instead of separate arguments, as well as some other things that need
cleaning up).

The intent of this function is to return a copy of the service's configuration,
and to copy / dereference the options in its configuration.
The code was doing this in slightly complicated fashion. This patch;
- adds a `copy()` function to serviceConfig
- rewrites the code to use a slightly more idiomatic approach, using one of
the approaches described in "golang SliceTricks" https://github.com/golang/go/wiki/SliceTricks#copy
- changes defaultService.ServiceConfig() to use this function, and updates
its godoc to better describe that it returns a copy.

This removes the ugly hack where we stored the current config, tried to
reconfigure the service, and rolled back to the stored copy on failures.

Most operations only require read access, so change this to use an RWMutex,
and some minor refactoring in lookupV2Endpoints() so that we are not
constructing tlsconfig multiple times in some cases.

This error was only returned in a single location, and not used anywhere
as a specific type.
The error returned by `validateNoScheme()` also appeared to only be used in
one case; in all other cases, the error itself was ignored, and replaced with
a custom error. Because of this, this patch also replace `validateNoScheme()`
with a `hasScheme()` function that returns a boolean, to better match how it's
used.

Un-export:
- config.LoadAllowNondistributableArtifacts()
- config.LoadInsecureRegistries()
- config.LoadMirrors()
The config type is already un-exported; this also un-exports these functions
to be explicit they're internal only.

These are only used internally, and the v1Endpoint.Path() function was only
used to get the `_ping` URL, so let's inline that code instead.

The DefaultService was not really meant to be used outside of the package, so
un-export it, and change NewService()'s signature to return a Service interface.
To un-export this type, a test in daemon/images was updated to not use DefaultService,
but now using the registry.Service interface itself.

While this was intended t be a stop-gap solution, it's been there for years and
users depend on this. It's also still complicated to secure _localhost_, so
by now, we'd probably have to be realistic, and consider this to be "permanent".

This is more in line with other consts that are used for defaults, and makes it
slightly easier to consume than DefaultV2Registry, e.g. see:
https://github.com/oras-project/oras-go/blob/v1.1.0/pkg/auth/docker/resolver.go#L81-L84
Note that both the "index.docker.io" and "registry-1.docker.io" domains
are here for historic reasons and backward-compatibility. These domains
are still supported by Docker Hub (and will continue to be supported), but
there are new domains already in use, and plans to consolidate all legacy
domains to new "canonical" domains. Once those domains are decided on, we
should update these consts (but making sure to preserve compatibility with
existing installs, clients, and user configuration).

From the field's description [1]:
DualStack previously enabled RFC 6555 Fast Fallback
support, also known as "Happy Eyeballs", in which IPv4 is
tried soon if IPv6 appears to be misconfigured and
hanging.
Deprecated: Fast Fallback is enabled by default. To
disable, set FallbackDelay to a negative value.
This field was deprecated in efc185029b,
which is included in Go 1.12beta1 and up.

I think it's a bit more readable to just use a literal value
for these; this also prevents having to use `_` to skip zero.

Some tests were using domain names that were intended to be "fake", but are
actually registered domain names (such as domain.com, registry.com, mytest.com).
Even though we were not actually making connections to these domains, it's
better to use domains that are designated for testing/examples in RFC2606:
