The use of pools here is unnecessary and creates a code dependency on
moby library which will move to internal.
The pool does not provide any value here since it is only done for a
single operation and unlikely performed in alongside other operations
which are re-using the buffers many times between garbage collections.

Currently the cp will tar from the same directory it will untar into
simultaneously. There is a race between reading the file and truncating
the file for write, however, the race will not show up with a large
enough buffer on the tar side if buffered before the copy begins.
Also removes the unnecessary deferred removal, the removal is handled by
cleanup and respects the no cleanup env.

This is a follow-up to 55e404e7a8, which
removed some warnings related to these fields.
These fields in the /info response were used to warn users if netfiltering
was not enabled on the host when the daemon started. Starting with
[moby@db25b0d], detecting whether netfiltering is enabled now
[happens when needed][1], making the state that's detected at startup
irrelevant.
These fields will therefore be deprecated in future, but we can start
removing their use in tests.

This patch:
- changes the test to use command-arguments instead of manually setting the
flag options; this also adds test-coverage for parsing actual command arguments.
- discards stdout/stderr of the command to prevent noise in test output

These warnings will no longer be returned by the daemon, so remove
them from the tests as well to make them more representative of

If STDOUT or STDERR are attached and the container exits, the streams
will be closed by the daemon while the container is exiting, causing
the streamer to return an error
61b02e636d/cli/command/container/hijack.go (L53)
that gets sent
61b02e636d/cli/command/container/run.go (L278)
and received
61b02e636d/cli/command/container/run.go (L225)
on `errCh`.
However, if only STDIN is attached, it's not closed (since this is
attached to the user's TTY) when the container exits, so the streamer
doesn't exit and nothing gets sent on `errCh`, meaning the CLI execution
hangs receiving on `errCh` on L231.
Change the logic to receive on both `errCh` and `statusChan` – this way,
if the container exits, we get notified on `statusChan` (even if only
STDIN is attached), and can cancel the streamer and exit.

Now, if running in "detached" mode, we early exit at L222.
Similarly, if `attachContainer` errors out, it returns an error that
gets handled on L190.
As such, `errCh` can never be nil on L231. Remove the nil check.

Since everything else after the `apiClient.ContainerStart` block is
under an `if attach` conditional, we can move the "detached" early exit
up.

During a `docker run`, the CLI has some different behavior/output
depending on whether the run is "detached" or not.
In some cases, the CLI is checking whether either `stdin`, `stdout` or
`stderr` are attached, but in other cases we're only checking `stdout`
and `stderr`, which leads to some inconsistencies:
```
$ docker run -a stdout --rm --name test alpine top
[docker kill test]
exit status 137
$ docker run -a stderr --rm --name test alpine top
[docker kill test]
exit status 137
$ docker run -a stdin --rm --name test alpine top
56820d94a89b96889478241ae68920323332c6d4cf9b51ba9340cba01e9e0565
[docker kill test]
[no exit code]
```
Since we're not checking for whether `stdin` is attached when deciding
whether to early exit without receiving on `statusChan`, the `docker run
-a stdin` is falling into the "detached mode" logic, which simply prints
the container ID and doesn't print/return the exit code.
This patch makes the "attached" checks consistent.

This patch fixes the context cancellation
behaviour for the `runContainer` function,
specifically the `createContainer` function
introduced in this commit 991b1303da.
It delays stripping the `cancel` from the context
passed into the `runContainer` function so that
the `createContainer` function can be cancelled
gracefully by a SIGTERM/SIGINT.
This is especially true when the requested image
does not exist and `docker run` needs to `pull`
the image before creating the container.
Although this patch does gracefully cancel
the `runContainer` function it does not address
the root cause. Some functions in the call path
are not context aware, such as `pullImage`.
Future work would still be necessary to ensure
a consistent behaviour in the CLI.

There's no need for `case=[xxx]` in table tests, Go does a good job of
formatting the test output and we're just adding the same information
for every test output line.

Instead of clearing the whole screen and then writing the new stats,
we now write the new stats on top of the old text, and then clear
the remaining text.
This is a more efficient way to update the stats, as it avoids the
flickering that happens when the screen is cleared and rewritten.

to use go1.23 semantics, which enabled the copyloopvar linter.
go1.22 now creates a copy of variables when assigned in a loop; make sure we

disabling that feature; https://go.dev/ref/spec#Go_1.22
