refactor: move from io/ioutil to io and os package
The io/ioutil package has been deprecated in Go 1.16. This commit

io and os packages.

b4e9b50765 layer/CreateRWLayerByGraphID: remove
This is an additon to commit 1fea38856a ("Remove v1.10 migrator")
aka PR #38265. Since that one, CreateRWLayerByGraphID() is not
used anywhere, so let's drop it.

Remove metadata store interface
Layer metadata storage has not been implemented outside of the layer
store and will be deprecated by containerd metadata storage. To prepare
for this and freeze the current metadata storage, remove the exported
interface and make it internal to the layer store.

ce8e529e18 LCOW: Re-coalesce stores
Signed-off-by: John Howard <jhoward@microsoft.com>

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.

0380fbff37 LCOW: API: Add platform to /images/create and /build
Signed-off-by: John Howard <jhoward@microsoft.com>

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.

f7f3d34210 Move CreateRWLayer() parameters in a struct
Move some of the optional parameters of CreateRWLayer() in a struct
called CreateRWLayerOpts. This will make it easy to add more options
arguments without having to change signature of CreateRWLayer().

This allows for easy extension of adding more parameters to existing
parameters list. Otherwise adding a single parameter changes code
at so many places.

pkg/archive: remove unnecessary Archive and Reader type
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.

50a498ea1c Verify layer tarstream
This adds verification for getting layer data out
of layerstore. These failures should only be possible
if layer metadata files have been manually changed
of if something is wrong with tar-split algorithm.

Failing early makes sure we don’t upload invalid data
to the registries where it would fail after someone
tries to pull it.

d04fa49a0d Refactor RWLayer to use referenced object instead of string
RWLayer will now have more operations and be protected through a referenced type rather than always looked up by string in the layer store.
Separates creation of RWLayer (write capture layer) from mounting of the layer.
This allows mount labels to be applied after creation and allowing RWLayer objects to have the same lifespan as a container without performance regressions from requiring mount.

500e77bad0 Add layer store
Layer store manages read-only and read-write layers on a union file system.
Read only layers are always referenced by content addresses.
Read-write layer identifiers are handled by the caller but upon registering
its difference, the committed read-only layer will be referenced by content
hash.
