remove unneeded "digest" alias for "go-digest"
I think this was there for historic reasons (may have been goimports expected
this, and we used to have a linter that wanted it), but it's not needed, so
let's remove it (to make my IDE less complaining about unneeded aliases).

image: remove leftover LCOW platform checks
This removes some of the checks that were added in 0cba7740d4,
but should no longer be needed.

- `image/store.Delete()`: no need to validate image platform to delete it.
- `image/tarexporter/takeLayerReference()`: use `image.OperatingSystem()` and
  fail early to prevent constructing the `ChainID()`.

35193c0e7d LCOW: Auto-select OS
Signed-off-by: John Howard <jhoward@microsoft.com>

Addresses https://github.com/moby/moby/pull/35089#issuecomment-367802698.
This change enables the daemon to automatically select an image under LCOW
that can be used if the API doesn't specify an explicit platform.

For example:

FROM supertest2014/nyan
ADD Dockerfile /

And docker build . will download the linux image (not a multi-manifest image)

And similarly docker pull ubuntu will match linux/amd64

f6a7763b6f Add Len() to image store for info endpoint
In info, we only need the number of images, but `CountImages` was
getting the whole map of images and then grabbing the length from that.
This causes a lot of unnecessary CPU usage and memory allocations, which
increases with O(n) on the number of images.

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.

ebcb7d6b40 Remove string checking in API error handling
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.

44e67adae5 image: Improve store locking
This showed up in a recent profile.

Search doesn't need to take a lock on the store, because digestset has
its own locking.

Some other methods can get by with a read lock instead of an exclusive
lock.

194eaa5c0f Add os_version and os_features to Image
These fields are needed to specify the exact version of Windows that an
image can run on. They may be useful for other platforms in the future.

This also changes image.store.Create to validate that the loaded image is
supported on the current machine. This change affects Linux as well, since
it now validates the architecture and OS fields.

01ba0a935b Add image store
The image store abstracts image handling. It keeps track of the
available images, and makes it possible to delete existing images or
register new ones. The image store holds references to the underlying
layers for each image.

The image/v1 package provides compatibility functions for interoperating
with older (non-content-addressable) image structures.
