The re-coalesces the daemon stores which were split as part of the
original LCOW implementation.
This is part of the work discussed in https://github.com/moby/moby/issues/34617,
in particular see the document linked to in that issue.
Instead of having to create a bunch of custom error types that are doing
nothing but wrapping another error in sub-packages, use a common helper
to create errors of the requested type.
e.g. instead of re-implementing this over and over:
```go
type notFoundError struct {
cause error
}
func(e notFoundError) Error() string {
return e.cause.Error()
}
func(e notFoundError) NotFound() {}
func(e notFoundError) Cause() error {
return e.cause
}
```
Packages can instead just do:
```
errdefs.NotFound(err)
```

This PR has the API changes described in https://github.com/moby/moby/issues/34617.
Specifically, it adds an HTTP header "X-Requested-Platform" which is a JSON-encoded
OCI Image-spec `Platform` structure.
In addition, it renames (almost all) uses of a string variable platform (and associated)
methods/functions to os. This makes it much clearer to disambiguate with the swarm
"platform" which is really os/arch. This is a stepping stone to getting the daemon towards
fully multi-platform/arch-aware, and makes it clear when "operating system" is being
referred to rather than "platform" which is misleadingly used - sometimes in the swarm
meaning, but more often as just the operating system.
Update logic to choose manifest from manifest list to check
for os version on Windows. Separate the logic for windows
and unix to keep unix logic the same.

Use strongly typed errors to set HTTP status codes.
Error interfaces are defined in the api/errors package and errors
returned from controllers are checked against these interfaces.
Errors can be wraeped in a pkg/errors.Causer, as long as somewhere in the
line of causes one of the interfaces is implemented. The special error
interfaces take precedence over Causer, meaning if both Causer and one
of the new error interfaces are implemented, the Causer is not
traversed.

The --allow-nondistributable-artifacts daemon option specifies
registries to which foreign layers should be pushed. (By default,
foreign layers are not pushed to registries.)
Additionally, to make this option effective, foreign layers are now
pulled from the registry if possible, falling back to the URLs in the
image manifest otherwise.
This option is useful when pushing images containing foreign layers to a
registry on an air-gapped network so hosts on that network can pull the
images without connecting to another server.

If a reference passed to the pull code contains both a tag and a digest,
currently the tag is used instead of the digest in the request to the
registry. This is the wrong behavior. Change it to favor the digest.

The diff id resolution currently relies on a stored mapping for
archive digest to diff id. This mapping could be derived from
the image configuration if the image configuration is available.
On linux the image config is pulled in parallel and may not be
available. On windows, however, it is always pulled first and can
be used to supplement the stored mapping for images which may not
have this mapping from being side loaded. This becomes useful when
combined with side loaded foreign layers.

As noted by #30083, the new strict checking of mediatypes misses some
cases where earlier bugs caused nonstandard mediatypes to be stored in
manifests. Two of the known cases are text/html and application/json,
which were returned by certain registries and stored by earlier versions
of Docker. Add special cases for text/html and application/json.

When storeLayer.Parent returns the parent layer, it needs to use the same logic as Get where it wraps in a describablyStoreLayer if the layer is describable. Otherwise, on Windows, this can result in pushing the foreign layers, which is not supposed to be allowed.

When building a manifest during a push operation, all layers must have
an associated descriptor. If a layer is missing a descriptor, that leads
to a panic.
A break inside a switch in layerAlreadyExists meant to break from the
loop surrounding the switch, but instead breaks from the switch. This
causes the loop to continue, and can overwrite the descriptor with an
empty one, leading to the panic.
Also, fix layerAlreadyExists not to abort the push when a speculative
stat on a candidate layer digest fails with an error. This could happen
in situations like a potential cross-repository mount where the user
does not have permission to access the source repository.

Remove the following comment in pullV2Tag:
// NOTE: not using TagService.Get, since it uses HEAD requests
// against the manifests endpoint, which are not supported by
// all registry versions.
This is actually not an issue, because TagService.Get does a fallback to
GET if HEAD fails. It has done this ever since TagService was added to
the distribution API, so this comment was probably based on an early
version of TagService before it was merged, or was always a
misunderstanding.
However, we continue to use ManifestService.Get instead because it
saves a round trip. The manifest can be retrieved directly instead of
resolving the digest first.

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`

from each layer into a single new layer and references all the parent's

Use a very limited number of mount attempts and no existence check for
small blobs. Use more attempts for bigger blobs.
