When running tests from my IDE, it compiles the tests before running,
then executes the compiled binary to run the tests. Cobra doesn't like that,
because in that situation os.Args is taken as argument for the command that's
executed. The command that's tested now sees the `test-` flags as arguments
(`-test.v -test.run ..`), which causes various tests to fail ("Command XYZ
does not accept arguments").
# compile the tests:
go test -c -o foo.test
# execute the test:
./foo.test -test.v -test.run TestFoo
=== RUN TestFoo
Error: "foo" accepts no arguments.
Set arguments to an empty slice to make sure it doesn't inherit arguments
from the test-binary.

This test was added in [moby@b2551c6] as part of a larger PR that implemented
unit tests in various packages. In this specific test, it looks like the
`imageSaveFunc` that's defined in the test-table was forgotten to be wired
up, causing all tests to effectively be skipped.
This patch wires up the function so that it's used in the test.

With this patch, completion is provided for `--platform` flags:
docker pull --platform<TAB>
linux linux/amd64 linux/arm/v5 linux/arm/v7 linux/arm64/v8 linux/riscv64 wasip1 windows
linux/386 linux/arm linux/arm/v6 linux/arm64 linux/ppc64le linux/s390x wasip1/wasm windows/amd64
Note that `docker buildx build` (with BuildKit) does not yet provide completion;
it's provided through buildx, and uses a different format (accepting multiple
comma-separated platforms). Interestingly, tab-completion for `docker build`
currently uses completion for non-buildkit, and has some other issues that may
have to be looked into.

Add a utility for completing platform strings.
Platforms offers completion for platform-strings. It provides a non-exhaustive
list of platforms to be used for completion. Platform-strings are based on
[runtime.GOOS] and [runtime.GOARCH], but with (optional) variants added. A
list of recognised os/arch combinations from the Go runtime can be obtained
through "go tool dist list".
Some noteworthy exclusions from this list:
- arm64 images ("windows/arm64", "windows/arm64/v8") do not yet exist for windows.
- we don't (yet) include `os-variant` for completion (as can be used for Windows images)
- we don't (yet) include platforms for which we don't build binaries, such as
BSD platforms (freebsd, netbsd, openbsd), android, macOS (darwin).
- we currently exclude architectures that may have unofficial builds,
but don't have wide adoption (and no support), such as loong64, mipsXXX,
ppc64 (non-le) to prevent confusion.

This commit adds tests for the commands
docker kill, docker commit, and docker
pause. Also, it creates the mock methods
of the docker client ContainerCommit and
ContainerPause so they can
be used in the tests.
For docker kill, it covers the
cases that:
- the command runs successfully
- the client returns an error
For docker commit, it covers

Move the code for parsing key-value files, such as used for
env-files and label-files to a separate package. This allows
other projects (such as compose) to use the same parsing
logic, but provide custom lookup functions for their situation
(which is slightly different).
The new package provides utilities for parsing key-value files
for either a file or an io.Reader. Most tests for EnvFile were
now testing functionality that's already tested in the new package,
so were (re)moved.

- the function already trimmed leading whitespace from each line before
parsing. keys with trailing whitespace would be invalidated, and values
have whitespace preserved, so there's no need to trim whitespace for the
key.
- if a line is validated (key is valid), we don't need to reconstruct the
key=value by concatenating, and we can add the line as-is.
- check if the key is empty before checking if it contains whitespace
- touch-up comments
- rename some variables for readability
- slight cleanup to use early returns / early continues to reduce nesting

This error was originally introduced `ErrBadEnvVariable` in [moby/moby@500c8ba],
but merely for convenience, and not used as a sentinel error. After the code
was moved from the daemon to the cli repository, it was renamed to be more
generic `ErrBadKey` in commit 2b17f4c8a8.
A search on GitHub shows that there's no consumers using this error as
sentinel error, and it's not used in our own code as such, so it should
be safe to remove this error.
This patch removes the `ErrBadKey` error-type; it also removes the prefix
(`poorly formatted environment:`) to make the error more generic, because
the same function was used both for env-files and label-files.

- Use gotest.tools for assertions
- Check for expected error messages
- Don't check for ErrBadKey errors, as it's not used
as a sentinel error anywhere.
- Use t.SetEnv() instead of depending on `HOME` being set
- Use t.TempDir() for writing temporary files

We used a hard-coded list of capabilities that we copied from containerd,
but the new "capability" package allows use to have a maintained list
of capabilities.
There's likely still some improvements to be made;
First of all, the capability package could provide a function to get the list
of strings.
On the completion-side, we need to consider what format is most convenient;
currently we use the canonical name (uppercase and "CAP_" prefix), however,
tab-completion is case-sensitive by default, so requires the user to type
uppercase letters to filter the list of options.
Bash completion provides a `completion-ignore-case on` option to make completion
case-insensitive (https://askubuntu.com/a/87066), but it looks to be a global
option; the current cobra.CompletionOptions also don't provide this as an option
to be used in the generated completion-script.
Fish completion has `smartcase` (by default?) which matches any case if
all of the input is lowercase.
Zsh does not have a dedicated option, but allows setting matching-rules
(see https://superuser.com/a/1092328).

This renames the `--time` flag as used on `docker stop` and `docker restart`
to `--timeout`, bringing it in line with other uses for this property,
such as `--stop-timeout` on `docker run`.
The `--time` option is deprecated and hidden, but will be kept for
backward compatibility, as these options existed for a long time.
