This uses the correct comparison with compatibility
checks for variants.
The deprecated arm variant matcher is left as is.
Although it is not needed for valid cases it is not
fully compatible as also matches some invalid
combinations, so should be removed separately.

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).

From the field's description [1]:
DualStack previously enabled RFC 6555 Fast Fallback
support, also known as "Happy Eyeballs", in which IPv4 is
tried soon if IPv6 appears to be misconfigured and
hanging.
Deprecated: Fast Fallback is enabled by default. To
disable, set FallbackDelay to a negative value.
This field was deprecated in efc185029b,
which is included in Go 1.12beta1 and up.

All uses of this interface already accept a DownloadDescriptor; keeping the
interface small to allow this functionality to be used by other download-descriptors,
while still being able to check for the actual functionality (to be able to register
a digest).

This is mostly for documentation purposes; defining a type makes
the option(s) show up grouped on pkg.go.dev (and in godoc).

The `TransferManager` interface only had a single implementation, and neither
`LayerDownloadManager`, nor `LayerUploadManager` currently had an option to
provide a custom implementation, so we can un-export this.

None of the implementations used return an error, so removing the error
return can simplify using these.

This argument was added for LCOW support, but it was only used to verify if
the passed platform (OS) matched the host. Given that all uses of this function
(except for one) passed runtime.GOOS, we may as well move the check to that
location.
We should do more cleaning up after this, and perform such validations early,
instead of passing platform around in too many places where it's only used for
similar validations. This is a first step in that direction.

This interface only had a single implementation (xfer.LayerDownloadManager),
and all places where it was used already imported the xfer package.
Removing the interface, also makes it a closer match to the "upload" part,
as `xfer.LayerUploadManager()` did not use an interface.

The io/ioutil package has been deprecated in Go 1.16. This commit
replaces the existing io/ioutil functions with their new definitions in
io and os packages.

Some registries seem to be non-conformant and return a not found error
when pulling by digest (which docker now does all the time).
To work around this, fallback when all of the following are true:
1. Image reference is a tag
2. Tag->digest resolution succeeds
3. Fetch by resolved digest fails with a "not found" error.
This is intentionally not caching the manifests to reduce complexity for
this edge case.

This allows us to cache manifests and avoid extra round trips to the
registry for content we already know about.
dockerd currently does not support containerd on Windows, so this does
not store manifests on Windows, yet.

The tag service does a `HEAD` request to get the manifest digest, where
we can then do a `GET` against the digest.
The `GET` by tag is not cacheable, but the `GET` against the digest is.
This allows proxies to work way better.

For CI, a temporary `DOCKER_ALLOW_SCHEMA1_PUSH_DONOTUSE` environment
variable was added while we work out a solution for testing schema 1
pulls (which currently require pushing them to a local registry first
for testing).

Currently we show this deprecation notice for any error returned by a
registry.
Registries can return an error for any number of reasons.
Instead let's show the deprecation notice only if the fallback was
successful.
