Starting with kernel v6.12, kernel memory TCP accounting is deprecated for cgroups v1.
Note: kernel memory TCP accounting is not supported by cgroups v2.

kernel-memory limits are not supported in cgroups v2, and were obsoleted in
[kernel v5.4], producing a `ENOTSUP` in kernel v5.16. Support for this option
was removed in runc and other runtimes, as various LTS kernels contained a
broken implementation, resulting in unpredictable behavior.
We deprecated this option in [moby@b8ca7de], producing a warning when used,
and actively ignore the option since [moby@0798f5f].
Given that setting this option had no effect in most situations, we should
just remove this option instead of continuing to handle it with the expectation
that a runtime may still support it.
Note that we still support RHEL 8 (kernel 4.18) and RHEL 9 (kernel 5.14). We
no longer build packages for Ubuntu 20.04 (kernel 5.4) and Debian Bullseye 11
(kernel 5.10), which still have an LTS / ESM programme, but for those it would
only impact situations where a runtime is used that still supports it, and
an old API version was used.

This package depends on jsonformatter.JSONProgress and jsonmessage.JSONMessage,
and it looks like it requires some of those for their stringer interface.

Move the type to the API, but embed it, so that we keep the
methods on the struct in this package.

We can probably use [aec.EmptyBuilder] for managing the output, but
currently we're doing it all manually, so defining some consts for
the basics we use.

It has no external users, and this package still has too many different
responsibilities, some of which may be available elsewhere, so moving it
internal so that we can decide to dismantle it further.

Remove the stub implementation for non-Windows platforms, and remove the
os.FileMode argument, which is ignored on Windows.

It has no external consumers, is written with specific behavior, making
it not a good candidate to carry in the module.
This moves it to the daemon as a non-exported `resolveSymlinkedDirectory`
utility, so that it's only accessible where it's currently used.

This package is used internally by the daemon, and was only used out
side of the daemon by pkg/plugins (for which we still need to look
where it should be kept).
Making it internal because it's trivial to implement if needed by
anyone. The only reason it's a package is to keep it central, and
to make it easier to discover where we have rootlesskit-specific
codepaths in our codebase.

pkg/stdcopy moved to github.com/moby/moby/api/stdcopy, and the 28.4
transitional releasee will provide an alias for those that use
github.com/docker/docker as dependency, so we can remove the alias
for the moby module.

The stringid package is used in many places; while it's trivial
to implement a similar utility, let's just provide it as a utility
package in the client, removing the daemon-specific logic.
For integration tests, I opted to use the implementation in the
client, as those should not ideally not make assumptions about
the daemon implementation.

This was added in 20d594fb79, but was
written before the API module was added. Now that the API is a separate
module, the check will no longer flag packages importing the API.

The stdcopy package is used to produce and read multiplexed streams for
"attach" and "logs". It is used both by the API server (to produce), and
the client (to read / de-multiplex).
Move it to the api package, so that it can be included in the api module.

This allows us to maintain GoDoc in a single place, and for
"Kill" and "Alive" to have consistent error-handling (Windows
does not support negative process-IDs).
