Commit 73aef6edfe
modified archive.ReplaceFileTarWrapper to set the Name field in the tar header,
if the field was not set.
That change exposed an issue in how a Dockerfile from stdin was sent to the daemon.
When attempting to build using a build-context, and a Dockerfile from stdin, the
following happened:
```bash
mkdir build-stdin && cd build-stdin && echo hello > hello.txt
DOCKER_BUILDKIT=0 docker build --no-cache -t foo -f- . <<'EOF'
FROM alpine
COPY . .
EOF
Sending build context to Docker daemon 2.607kB
Error response from daemon: dockerfile parse error line 1: unknown instruction: .DOCKERIGNORE
```
Removing the `-t foo`, oddly lead to a different failure:
```bash
DOCKER_BUILDKIT=0 docker build --no-cache -f- . <<'EOF'
FROM alpine
COPY . .
EOF
Sending build context to Docker daemon 2.581kB
Error response from daemon: Cannot locate specified Dockerfile: .dockerfile.701d0d71fb1497d6a7ce
```
From the above, it looks like the tar headers got mangled, causing (in the first
case) the daemon to use the build-context tar as a plain-text file, and therefore
parsing it as Dockerfile, and in the second case, causing it to not being able to
find the Dockerfile in the context.
I noticed that both TarModifierFuncs were using the same `hdrTmpl` struct, which
looks to caused them to step on each other's toes. Changing them to each initialize
their own struct made the issue go away.
After this change:
```bash
DOCKER_BUILDKIT=0 docker build --no-cache -t foo -f- . <<'EOF'
FROM alpine
COPY . .
EOF

Some tests were using domain names that were intended to be "fake", but are
actually registered domain names (such as mycorp.com).
Even though we were not actually making connections to these domains, it's
better to use domains that are designated for testing/examples in RFC2606:

On Windows, the os/exec.{Command,CommandContext,LookPath} functions
resolve command names that have neither path separators nor file extension
(e.g., "git") by first looking in the current working directory before
looking in the PATH environment variable.
Go maintainers intended to match cmd.exe's historical behavior.
However, this is pretty much never the intended behavior and as an abundance of precaution
this patch prevents that when executing commands.
Example of commands that docker.exe may execute: `git`, `docker-buildx` (or other cli plugin), `docker-credential-wincred`, `docker`.
Note that this was prompted by the [Go 1.15.7 security fixes](https://blog.golang.org/path-security), but unlike in `go.exe`,
the windows path lookups in docker are not in a code path allowing remote code execution, thus there is no security impact on docker.

This hack was added in an attempt to continue supporting the experimental
(non-buildkit) `--platform` option, by dynamically updating the API version
required if buildkit isn't enabled.
This hack didn't work, however, because at the moment the override is
added, the command is not yet attached to the "root" (`docker`) command,
and because of that, the command itself is the `root` command;
`cmd.Root()` returned the `build` command.
As a result, validation steps defined as `PersistentPreRunE` on the root
command were not executed, causing invalid flags/options to not producing
an error.
Attempts to use an alternative approach (for example, cobra supports both
a `PersistentPreRun` and `PersistentPreRunE`) did not work either, because
`PersistentPreRunE` takes precedence over `PersistentPreRun`, and only one
will be executed.
Now that `--platform` should be supported for other cases than just for
experimental (LCOW), let's remove the 'experimental' check, and just assume
it's supported for API v1.32 and up.

While performance will be worse, we can safely ignore the --stream
option when used, and print a deprecation warning instead of failing
the build.
With this patch:
echo -e "FROM scratch\nLABEL foo=bar" | docker build --stream -
DEPRECATED: The experimental --stream flag has been removed and the build context
will be sent non-streaming. Enable BuildKit instead with DOCKER_BUILDKIT=1
to stream build context, see https://docs.docker.com/go/buildkit/

The `docker push` command up until [v0.9.1](https://github.com/moby/moby/blob/v0.9.1/api/client.go#L998)
always pushed all tags of a given image, so `docker push foo/bar` would push (e.g.)
all of `foo/bar:latest`, `foo:/bar:v1`, `foo/bar:v1.0.0`.
Pushing all tags of an image was not desirable in many case, so docker v0.10.0
enhanced `docker push` to optionally specify a tag to push (`docker push foo/bar:v1`)
(see https://github.com/moby/moby/issues/3411 and the pull request that implemented
this: https://github.com/moby/moby/pull/4948).
This behavior exists up until today, and is confusing, because unlike other commands,
`docker push` does not default to use the `:latest` tag when omitted, but instead
makes it push "all tags of the image"
For example, in the following situation;
```
docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
thajeztah/myimage latest b534869c81f0 41 hours ago 1.22MB
```
Running `docker push thajeztah/myimage` seemingly does the expected behavior (it
pushes `thajeztah/myimage:latest` to Docker Hub), however, it does not so for the
reason expected (`:latest` being the default tag), but because `:latest` happens
to be the only tag present for the `thajeztah/myimage` image.
If another tag exists for the image:
```
docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
thajeztah/myimage latest b534869c81f0 41 hours ago 1.22MB
thajeztah/myimage v1.0.0 b534869c81f0 41 hours ago 1.22MB
```
Running the same command (`docker push thajeztah/myimage`) will push _both_ images
to Docker Hub.
> Note that the behavior described above is currently not (clearly) documented;
> the `docker push` reference documentation (https://docs.docker.com/engine/reference/commandline/push/)
does not mention that omitting the tag will push all tags
This patch changes the default behavior, and if no tag is specified, `:latest` is
assumed. To push _all_ tags, a new flag (`-a` / `--all-tags`) is added, similar
to the flag that's present on `docker pull`.
With this change:
- `docker push myname/myimage` will be the equivalent of `docker push myname/myimage:latest`
- to push all images, the user needs to set a flag (`--all-tags`), so `docker push --all-tags myname/myimage:latest`

As pointed out in #1459, docker cli fails to detect that the input is a tarball,
in case it is generated by `git archive --format=tgz`.
This happens because `git archive` adds some metadata to the initial tar header,
and so it is more than 1 block (of 512 bytes) long, while we only provide 1 block
to archive/tar.Next() and it fails.
To fix, give it 2 blocks :)
