This fix tries to fix 29667 where image's `CMD` is modified
after `WORKDIR` in Dockerfile.
The value of `b.runConfig.Cmd` was modified in the processing
of `WORKDIR`, in order to fix 28902. However, the same
`b.runConfig.Cmd` is passed to `commit()`.
This fix restored the `b.runConfig.Cmd` before `commit()`
the image for `WORKDIR`.
A test has been added.
This fix fixes 29667.
This fix is related to 28902, 28909, 28514.

This fix tries to fix the issue in 29619 where
labels passed from `build --labels` are not sorted.
As a result, if multiple labels have been passed,
each `docker build --labels A=A --labels B=B --labels C=C`
will generate different layers.
This fix fixes the issue by sort the Labels before
they are concatenated to `LABEL ...`.
A unit test has been added to cover the changes

This reverts 26103. 26103 was trying to make it so that if someone did:
docker build --build-arg FOO .
and FOO wasn't set as an env var then it would pick-up FOO from the
Dockerfile's ARG cmd. However, it went too far and removed the ability
to specify a build arg w/o any value. Meaning it required the --build-arg
param to always be in the form "name=value", and not just "name".
This PR does the right fix - it allows just "name" and it'll grab the value
from the env vars if set. If "name" isn't set in the env then it still needs
to send "name" to the server so that a warning can be printed about an
unused --build-arg. And this is why buildArgs in the options is now a
*string instead of just a string - 'nil' == mentioned but no value.
Closes#29084

Allow built images to be squash to scratch.
Squashing does not destroy any images or layers, and preserves the
build cache.
Introduce a new CLI argument --squash to docker build
Introduce a new param to the build API endpoint `squash`
Once the build is complete, docker creates a new image loading the diffs
from each layer into a single new layer and references all the parent's
layers.

As is seem in the comment of `normaliseWorkdir` for windows:
```
...
// WORKDIR c:\\foo --> C:\foo
// WORKDIR \\foo --> C:\foo
...
```
However, this is not the case in the current implementation because
`filepath.FromSlash` is used and `FromSlash` does not replace multiple
separator with a single one (`file.Clean` does).
So `normaliseWorkdir` does not truly normalize workdir.
This fix changes the implementation of `normaliseWorkdir` and use
`filepath.Clean` instead of `filepath.FromSlash`.
Additional test cases have been added to the unit test.

with an empty line after escape.
An additional integration test has been added.

While look at #27039 I noticed that we allow for whitespace after
the continuation char (\\) which is wrong. It needs to be the very
last char in the line.

This fix tries to address the issue raised in 26453 where bad syntax
on dockerfile is not checked before building, thus user has to wait
before seeing error in dockerfile.
This fix fixes the issue by evaluating all the instructions and check
syntax before dockerfile is invoked actually.
All existing tests pass.

We attached the JSON flag to the wrong AST node, causing Docker to treat
the exec form ["binary", "arg"] as if the shell form "binary arg" had
been used. This failed if "ls" was not present.
Added a test to detect this.
Fixes#26174

The error message suggests you need one argument even when you
have provided one. Suggest having another argument.
