Manifest is now generated during a v2 push, not relying on previously generated hashes. When pushing a layer, the hash is directly calculated from the tar contents which will be pushed. Computing the hash on push ensures that the hash contents always match what is seen by the registry. This also mitigates issues with tarsum differences and permits using pure SHA digests.
Additionally the new manifest function is moved to the unit tests since it is no longer called outside the tests.

The call to io.Copy was not being checked for errors at a critical point in the
pull logic. This patch will log the error value if not nil.

pushV2Image() calls TarLayer() which returns an archive. One needs to
Close() the archive once done otherwise it will leave mounted devices
if devicemapper graph driver is being used.

manifest code calls TarLayer() and gets archive. This archive needs to
be closed once caller is done using it to release the resrouces held
by archive. For the devicemapper graphdriver, archive keeps a device
mounted (device which is backing the layer). If archive.Close() is not
called, that device remains mounted and later deletion of device fails
leading to various other issues.

The trust graph currently pulls the keys needed to verify official images. For non-official images this graph check is useless. To avoid hitting the key statement url when pulling from private v2 registries, restrict the check to official image pulls.

Pushing by image ID is not allowed in the Docker CLI and not supported by the registry. An unnamed image also cannot be pushed to a private registry, since no endpoint is specified and it will default to the hub. The hub also does not support this use case, therefore removing the code path is the best solution.
The ability to push a layer without a name is unsupported by the v2 registry.

Only show the verification message if all the tarsum checks pass and the image manifest is verified.
No longer return an error when a tarsum verification fails, just reset the verification flag.
Tarsum verification is less meaningful without a verified manifest and therefore it should not cause an error.
Updated the verified image test to pull an image which expected to have a verified manifest and contents.

It didn't work on v2 anyways. And an image with a lot of aliases was slow to

When requesting a token, the basic auth header is always being set even
if there is no username value. This patch corrects this and does not set
the basic auth header if the username is empty.
Also fixes an issue where pulling all tags from a v2 registry succeeds
when the image does not actually exist on the registry.

Before the V2 registry changes, images with no config could be pushed.
This change fixes a regression that made those images not able to be
