Ensure that layers are not excluded from manifests based on previous pushes.
Continue skipping pushes on layers which were pushed by a previous tag.
Update push multiple tag tests.
Ensure that each tag pushed exists on the registry and is pullable.
Add output comparison on multiple tag push check.

The Docker Daemon should send actual actions client ask for to issue tokens,
not all the permissions that client is guaranteed.

Previously, its other return value was used even when it returned an
error. This is awkward and goes against the convention. It also could
have resulted in a nil pointer dereference when an error was returned
because of an unknown pool type. This changes the unknown pool type
error to a panic (since the pool types are hardcoded at call sites and
must always be "push" or "pull"), and returns a "found" boolean instead
of an error.

The practice of buffering to a tempfile during a pushing contributes massively
to slow V2 push performance perception. The protocol was actually designed to
avoid precalculation, supporting cut-through data push. This means we can
assemble the layer, calculate its digest and push to the remote endpoint, all
at the same time.
This should increase performance massively on systems with slow disks or IO
bottlenecks.

Some structures use int for sizes and UNIX timestamps. On some
platforms, int is 32 bits, so this can lead to the year 2038 issues and
overflows when dealing with large containers or layers.
Consistently use int64 to store sizes and UNIX timestamps in
api/types/types.go. Update related to code accordingly (i.e.
strconv.FormatInt instead of strconv.Itoa).
Use int64 in progressreader package to avoid integer overflow when
dealing with large quantities. Update related code accordingly.

Add a trusted flag to force the cli to resolve a tag into a digest via the notary trust library and pull by digest.
On push the flag the trust flag will indicate the digest and size of a manifest should be signed and push to a notary server.
If a tag is given, the cli will resolve the tag into a digest and pull by digest.
After pulling, if a tag is given the cli makes a request to tag the image.
Use certificate directory for notary requests
Read certificates using same logic used by daemon for registry requests.
Catch JSON syntax errors from Notary client
When an uncaught error occurs in Notary it may show up in Docker as a JSON syntax error, causing a confusing error message to the user.
Provide a generic error when a JSON syntax error occurs.
Catch expiration errors and wrap in additional context.

pushV2Tag already deduplicates layers, but the scope of this
deduplication is only for a particular tag. If we are pushing all tags
in a repository, we may check layers several times. Fix this by moving
the layersSeen map from the pushV2Tag function to the v2Pusher struct.
In addition to avoiding some useless round-trips, this makes the "docker
push" output less confusing. It formerly could contain many repeated
lines like:
124e2127157f: Image already exists
124e2127157f: Image already exists
...
Add test coverage based on the "docker push" output: a hash should not
appear multiple times when pushing multiple tags.
