This moves the blobs around so they follow the OCI spec.
Note that because docker reads paths from the manifest.json inside the
tar this is not a breaking change.
This does, however, remove the old layer "VERSION" file which had a big
"why is this even here" in the code comments. I suspect it does not
matter at all even for really old versions of Docker. In any case it is
a useless file for any even relatively modern version of Docker.

TestProxyNXDOMAIN has proven to be susceptible to failing as a
consequence of unlocked threads being set to the wrong network
namespace. As the failure mode looks a lot like a bug in the test
itself, it seems prudent to add a check for mismatched namespaces to the
test so we will know for next time that the root cause lies elsewhere.

osl.setIPv6 mistakenly captured the calling goroutine's thread's network
namespace instead of the network namespace of the thread getting its
namespace temporarily changed. As this function appears to only be
called from contexts in the process's initial network namespace, this
mistake would be of little consequence at runtime. The libnetwork unit
tests, on the other hand, unshare network namespaces so as not to
interfere with each other or the host's network namespace. But due to
this bug, the isolation backfires and the network namespace of
goroutines used by a test which are expected to be in the initial
network namespace can randomly become the isolated network namespace of
some other test. Symptoms include a loopback network server running in
one goroutine being inexplicably and randomly being unreachable by a
client in another goroutine.
Capture the original network namespace of the thread from the thread to
be tampered with, after locking the goroutine to the thread.

Swapping out the global logger on the fly is causing tests to flake out
by logging to a test's log output after the test function has returned.
Refactor Resolver to use a dependency-injected logger and the resolver
unit tests to inject a private logger instance into the Resolver under
test.

tstwriter mocks the server-side connection between the resolver and the
container, not the resolver and the external DNS server, so returning
the external DNS server's address as w.LocalAddr() is technically
incorrect and misleading. Only the protocols need to match as the
resolver uses the client's choice of protocol to determine which
protocol to use when forwarding the query to the external DNS server.
While this change has no material impact on the tests, it makes the
tests slightly more comprehensible for the next person.

commit 0abb8dec3f removed support for
running overlay/overlay2 on top of a backing filesystem without d_type
support, and turned it into a fatal error when starting the daemon,
so there's no need to generate warnings for this situation.

Extended attributes are set on files in container images for a reason.
Fail to unpack if extended attributes are present in a layer and setting
the attributes on the unpacked files fails for any reason.
Add an option to the vfs graph driver to opt into the old behaviour
where ENOTSUPP and EPERM errors encountered when setting extended
attributes are ignored. Make it abundantly clear to users and anyone
triaging their bug reports that they are shooting themselves in the
foot by enabling this option.

Our resolver is just a forwarder for external DNS so it should act like
it. Unless it's a server failure or refusal, take the response at face
value and forward it along to the client. RFC 8020 is only applicable to
caching recursive name servers and our resolver is neither caching nor
recursive.

This fixes a bug where, if a user pulls an image with a tag != `latest` and
a specific platform, we return an NotFound error for the wrong (`latest`) tag.
see: https://github.com/moby/moby/issues/45558
This bug was introduced in 779a5b3029
in the changes to `daemon/images/image_pull.go`, when we started returning the error from the call to
`GetImage` after the pull. We do this call, if pulling with a specified platform, to check if the platform
of the pulled image matches the requested platform (for cases with single-arch images).
However, when we call `GetImage` we're not passing the image tag, only name, so `GetImage` assumes `latest`
which breaks when the user has requested a different tag, since there might not be such an image in the store.

Allow empty request bodies for this endpoint once again.

The internal Client request methods which accept an object as a body use
nil to signal that the request should not have a body. But it is easy to
accidentally pass a typed-nil value as the object, e.g. if the object
comes from a function argument or struct field of a concrete type. The
result is that these requests will, surprisingly, have a JSON body of
`null`. Treat typed-nil pointers the same as untyped nils for the
purposes of determining whether or not the request should include a
body.
Stop assuming that POST requests should always have a body. POST /commit
does not require a body, for example.

Upstart has been EOL for 8 years and isn't used by any distributions we support any more.
Additionally, this removes the "cgroups v1" setup code because it's more reasonable now for us to expect something _else_ to have set up cgroups appropriately (especially cgroups v2).

These changes add basic CDI integration to the docker daemon.
A cdi driver is added to handle cdi device requests. This
is gated by an experimental feature flag and is only supported on linux
This change also adds a CDISpecDirs (cdi-spec-dirs) option to the config.
This allows the default values of `/etc/cdi`, /var/run/cdi` to be overridden
which is useful for testing.
