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.
This enables docker cp and ADD/COPY docker build support for LCOW.
Originally, the graphdriver.Get() interface returned a local path
to the container root filesystem. This does not work for LCOW, so
the Get() method now returns an interface that LCOW implements to
support copying to and from the container.

Changes most references of syscall to golang.org/x/sys/
Ones aren't changes include, Errno, Signal and SysProcAttr
as they haven't been implemented in /x/sys/.

[s390x] switch utsname from unsigned to signed
per 33267e036f

change the buildtags

This fixes https://github.com/docker/docker/issues/30278 where
there is a race condition in HCS for RS1 and RS2 builds, and enumeration
of compute systems can return access is denied if a silo is being
torn down in the kernel while HCS is attempting to enumerate them.
This allows for easy extension of adding more parameters to existing
parameters list. Otherwise adding a single parameter changes code
at so many places.

The `archive` package defines aliases for `io.ReadCloser` and
`io.Reader`. These don't seem to provide an benefit other than type
decoration. Per this change, several unnecessary type cases were
removed.

The Windows BCD store for the utility VM is mutated during layer import,
which causes failures in docker save. Back up the BCD store and related
log files so that save has access to their original contents.
Fixes#25893.

Now that Windows base images can be loaded directly into docker via "docker load" of a specialized tar file (with docker pull support on the horizon) we no longer have need of the custom images code path that loads images from a shared central location. Removing that code and it's call points.

This improves reliability by doing parsing of potentially untrusted data
in a separate process. It opens the door for further security improvements
if we can lock down the reexec-ed process. It also improves import
performance by only taking the backup and restore privileges once, for the
whole process.

In TP5, Hyper-V containers need all image files ACLed so that the virtual
machine process can access them. This was fixed post-TP5 in Windows, but
for TP5 we need to explicitly add these ACLs.

This adds support to the Windows graph driver for ApplyDiff on a base
layer. It also adds support for hard links, which are needed because the
Windows base layers double in size without hard link support.
