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.

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.
Issue Description:
* 1. Saving more than one images, `docker save -o a.tar aaa bbb`
* 2. Delete the last image which in saving progress. `docker rmi bbb`
Espected:
Saving images operation shouldn't be disturbed. But the real result is that failed to
save image and get an error as below:
`Error response from daemon: open
/var/lib/docker/image/devicemapper/imagedb/content/sha256/7c24e4d533a76e801662ad1b7e6e06bc1204f80110b5623e96ba2877c51479a1:
no such file or directory`
Analysis:
1. While saving more than one images, it will get all the image info from reference/imagestore,
and then using the `cached data` to save the images to a tar file.
2. But this process doesn't have a resource lock, if a deletion operation comes, the image will be deleted,
so saving operation will fail.
Solution:
When begin to save an image, `Get` all the layers first. then the
deletion operation won't delete the layers.

Remove forked reference package. Use normalized named values
everywhere and familiar functions to convert back to familiar
strings for UX and storage compatibility.
Enforce that the source repository in the distribution metadata
is always a normalized string, ignore invalid values which are not.
Update distribution tests to use normalized values.

After https://github.com/docker/docker/pull/28926, if saving multiple images
which have common layers at same time, the common layers can't share in the tar archive
because the hash ID changes because of the Create time. The Create time is used for
pre v1.9 which treat each layer as a image and make no sense for after v1.10.
To make the hash ID consistent and keep the image save from >1.10 working properly
on pre v1.9, using a constant Create time `time.Unix(0,0)`.

The `digest` data type, used throughout docker for image verification
and identity, has been broken out into `opencontainers/go-digest`. This
PR updates the dependencies and moves uses over to the new type.

This fix tries to address the issue raised in 25529 wehre the
image/load API returns `application/json` for quiet=0 and
`text/plain` for quite=1.
This fix makes the change so that `application/json` is returned
for both quiet=0 and quite=1.
This fix has been tested manually.
This fix fixes 25529.

Relative paths are now calculated from a base path rather than from the file path, which gets treated like a directory.
Symlinks will now properly point to the file as "../<layer dir>/layer.tar" rather the incorrect "../../<layer dir>/layer.tar".
Fixes#24951

When calling docker load on an image tar containing a compressed layer,
apply NewProgressReader to the compressed layer (whose size is known), not
the uncompressed stream. This fixes progress reporting to the client in
this case.

During a `docker load` there are times when nothing is printed
to the screen, leaving the user with no idea whether something happened.
When something *is* printed, often its just something like:
```
1834950e52ce: Loading layer 1.311 MB/1.311 MB
5f70bf18a086: Loading layer 1.024 kB/1.024 kB
```
which isn't necessarily the same as the image IDs.
This PR will either show:
- all of the tags for the image, or
- all of the image IDs if there are no tags
Sample output:
```
$ docker load -i busybox.tar
Loaded image: busybox:latest
$ docker load -i a.tar
Loaded image ID: sha256:47bcc53f74dc94b1920f0b34f6036096526296767650f223433fe65c35f149eb
```
IOW, show the human-friendly stuff first and then only if there are no tags
default back to the image IDs, so they have something to work with.
For me this this is needed because I have lots of images and after a
recent `docker load` I had no idea what image I just imported and had a
hard time figuring it out. This should fix that by telling the user
which images they just imported.
I'll add tests once there's agreement that we want this change.

Save was failing file integrity checksums due to bugs in both
Windows and Docker. This commit includes fixes to file time handling
in tarexport and system.chtimes that are necessary along with
the Windows platform fixes to correctly support save. With this
change, sysfile_backups for windowsfilter driver are no longer
needed, so that code is removed.
