The `--tlscacert`, `--tlscert`, and `--tlskey` command-line flags had
non-standard behavior for handling values contained in quotes (`"` or `'`).
Normally, quotes are handled by the shell, for example, in the following
example, the shell takes care of handling quotes before passing the values
to the `docker` CLI:
docker --some-option "some-value-in-quotes" ...
However, when passing values using an equal sign (`=`), this may not happen
and values may be handled including quotes;
docker --some-option="some-value-in-quotes" ...
This caused issues with "Docker Machine", which used this format as part
of its `docker-machine config` output, and the CLI carried special, non-standard
handling for these flags.
Docker Machine reached EOL, and this special handling made the processing
of flag values inconsistent with other flags used, so this behavior is
deprecated. Users depending on this behavior are recommended to specify
the quoted values using a space between the flag and its value, as illustrated
above.

hostVar is used for the '--host' / '-H' flag to set [ClientOptions.Hosts].
The [ClientOptions.Hosts] field is a slice because it was originally shared
with the daemon config. However, the CLI only allows for a single host to
be specified.
hostVar presents itself as a "string", but stores the value in a string
slice. It produces an error when trying to set multiple values, matching
the check in [getServerHost].

The ClientOptions struct and related flags were inherited from the Moby
repository, where originally the CLI and Daemon used the same implementation
and had a "Common" options struct. When the CLI moved to a separate repository,
those structs were duplicated, but some daemon-specific logic remained. For
example, the daemon can be configured to listen on multiple ports and sockets
([moby@dede158]), but the CLI [can only connect to a single host][1]. The
daemon config also had to account for flags conflicting with `daemon.json`,
and use special flag-vars for this ([moby@677a6b3]).
Unfortunately, the `ClientConfig` struct became part of the public API and
is used as argument in various places, but we can remove the use of the
special flag var. This patch replaces the use of `NewNamedListOptsRef`
for a regular `StringArray`.
Unfortunately this changes the flag's type description from `list` to
`stringArray`, but we can look at changing that separately.

The example shows that the `--volumes` option is used, which in current
versions of docker only removes "anonymous" volumes, but preserves named
volume:
$ docker system prune -a --volumes
...
- all anonymous volumes not used by at least one container
...
But the example output showed that a named volume ("named-vol") was
deleted;

Plugins are not widely used, and there's no known plugins that use
content-trust. We're working on updating the authentication stack
in the CLI, and the trust implementation hinders us in making
changes, so removing parts that are not high-priority (ahead of
full deprecation of DCT).

The `bind-nonrecursive` option was replaced with the [`bind-recursive`]
option (see [cli-4316], [cli-4671]). The option was still accepted, but
printed a deprecation warning:
bind-nonrecursive is deprecated, use bind-recursive=disabled instead
In the v29.0 release, this warning is removed, and returned as an error.
Users should use the equivalent `bind-recursive=disabled` option instead.

Docker Content Trust is currently only implemented for the classic
builder, but is known to not work with multi-stage builds, and
requires rewriting the Dockerfile, which is brittle because the
Dockerfile syntax evolved with the introduction of BuildKit as
default builder.
Given that the classic builder is deprecated, and only used for
Windows images, which are not verified by content trust;
# docker pull --disable-content-trust=false mcr.microsoft.com/windows/servercore:ltsc2025
Error: remote trust data does not exist for mcr.microsoft.com/windows/servercore: mcr.microsoft.com does not have trust data for mcr.microsoft.com/windows/servercore
With content trust not implemented in BuildKit, and not implemented
in docker compose, this resulted in an inconsistent behavior.
This patch removes content-trust support for "docker build". As this
is a client-side feature, users who require this feature can still
use an older CLI to to start the build.

Adds a flag to the create and run command, `--use-api-socket`, that can
be used to start a container with the correctly configured parameters to
ensure that accessing the docker socket will work with out managing bind
mounts and authentication injection.
The implementation in this PR resolves the tokens for the current
credential set in the client and then copies it into a container at the
well know location of /run/secrets/docker/config.json, setting
DOCKER_CONFIG to ensure it is resolved by existing tooling. We use a
compose-compatible secret location with the hope that the CLI and
compose can work together seamlessly.
The bind mount for the socket is resolved from the current context,
erroring out if the flag is set and the provided socket is not a unix
socket.
There are a few drawbacks to this approach but it resolves a long
standing pain point. We'll continue to develop this as we understand
more use cases but it is marked as experimental for now.

The [`docker buildx bake`][1] command has reached GA; this patch adds
a top-level `docker bake` command as alias for `docker buildx bake` to
improve discoverability and make it more convenient to use.
With this patch:
docker --help
Usage: docker [OPTIONS] COMMAND
A self-sufficient runtime for containers
Common Commands:
run Create and run a new container from an image
exec Execute a command in a running container
ps List containers
build Build an image from a Dockerfile
bake Build from a file
pull Download an image from a registry
push Upload an image to a registry
images List images
...
The command is hidden if buildx is not installed;
